AK47 Geplaatst January 16, 2020 Auteur Rapporteren Share Geplaatst January 16, 2020 I did more dismantling of the front of the Jeep today (nice weather outside). With the front grill and the top metal bar removed, I am able to lift the compressor out of the way. I'm doing this so I don't have to release freon. Next task is ro remove timing chain cover and finally the camshaft. Citeren Link naar opmerking Deel via andere websites More sharing options...

AK47 Geplaatst January 16, 2020 Auteur Rapporteren Share Geplaatst January 16, 2020 Thanks @Kapt. Bob. It's indeed a lot of work to get to the camshaft. And I'm only working on it during good weather so it's a bit slow. I also meant to say condenser instead of compressor. I haven't added R-12 freon since I bought the Jeep in 1994 and it still blows a cool (not cold) air. But is is good enough for now. I wonder how much it would cost for freon to be added. When I lived in Alaska for 21 years, I never really used the A/C. I just opened my window in the summers. Citeren Link naar opmerking Deel via andere websites More sharing options...
AK47 Geplaatst January 19, 2020 Auteur Rapporteren Share Geplaatst January 19, 2020 So frustrating to find out that the distributor needs a gasket which I don't have. I have planned for almost everything that I needed for the engine before I left the US two and a half years ago. I am going to wait to pull the crankshaft until after I get the distributor gasket here. I wish there was a Napa or AutoZone nearby. Ah well... maybe I can just run a bead of black RTV sealant. Has anyone done that before? Citeren Link naar opmerking Deel via andere websites More sharing options...
AK47 Geplaatst January 19, 2020 Auteur Rapporteren Share Geplaatst January 19, 2020 RTV is okay to use based on reading a couple of Jeep Cherokee forums. So I guess I'll keep on going. 👍 Citeren Link naar opmerking Deel via andere websites More sharing options...
Ab Geplaatst January 20, 2020 Rapporteren Share Geplaatst January 20, 2020 There are some good suppliers for Jeep parts around in the Netherlands. They ship the same day, so it will be in your place the next day if your lucky..... Jeep parts.nl 4offroad 4Low B&S autoparts They all have a online webshop, just give a call when your part is not available there. Most off the time it's available within a few days.

AK47 Geplaatst January 20, 2020 Auteur Rapporteren Share Geplaatst January 20, 2020 Thanks for the tip, @Ab! I'll check them out if I'm in a bind. So, I removed the distributor and cleaned it. Will replace using black RTV. I also installed the new camshaft with lots of Clevite cam lube. I cleaned the tappet bores with an old brass shotgun barrel brush that I had lying around. It helped a lot with the camshaft installation when I attached the sprocket and used it as a handle. I am still going to be very mindful that there is a small nick on the front bearing that I saw when I removed the original camshaft. However, it slid in nicely. So I may have to do a teardown in the next couple of years. Citeren Link naar opmerking Deel via andere websites More sharing options...

REAL STRANGLER Geplaatst January 20, 2020 Rapporteren Share Geplaatst January 20, 2020 Don t forget to soak the lifters in clean engine oil, preferably a night over! Success, Siert. Citeren Link naar opmerking Deel via andere websites More sharing options...

I honestly don't remember how tight it was when I installed it. And now that you mentioned it @Arjanw I will have to verify. My logbook will tell me when I changed it but it may have been about 100,000 miles (160,000 km) ago. In that case, it might be due for a change. The tensioner spring was extended but not to its fullest so I may have some more miles to go, and I haven't heard any chain slap (yet) 🙄. Today, I just cleaned old gasket from the timing chain cover and aligned the TDC on the sprockets and harmonic balancer. I pulled the distributor out to double-check where the rotor was pointing. I think I will reinstall the distributor tomorrow. The FSM calls for the oil pump screw to be in a specific orientation with respect to the block. I may have gotten it wrong yesterday. Oh well, I'll have to read up again on it. Yep, I will soak the lifters in oil @REAL STRANGLER. I bought a 5L jug of dinosaur oil 10W50. I read that it's best to do this before going back to Mobil1 synthetic oil I normally use. At least for the first 500 miles (800 km). I looked in my spare supplies and I have 2 oil filters so I'm good. Will have to buy new ones locally after that. Citeren Link naar opmerking Deel via andere websites More sharing options...
AK47 Geplaatst January 22, 2020 Auteur Rapporteren Share Geplaatst January 22, 2020 Hmmm. I just checked my logbook and it shows I changed my timing chain, the tensioner, the oil seal, and the cover on 01 Nov 2015. It seems too soon to change it again. I'll keep an eye on it. The tensioner spring looks halfway deployed so it should last another five years. We'll see. Citeren Link naar opmerking Deel via andere websites More sharing options...
AK47 Geplaatst January 23, 2020 Auteur Rapporteren Share Geplaatst January 23, 2020 So the head is now back on the block. What a PITA to lift that thing over the engine bay and then line it up to the guide pins. New head bolts installed and torqued to spec.

AK47 Geplaatst January 24, 2020 Auteur Rapporteren Share Geplaatst January 24, 2020 One of my rocker arms was slightly twisted so I used a locking vise grip to hold it and twist. I saw this in a video and it worked. I also bolted the exhaust and intake manifolds. So far assembly is the reverse of disassembly. Getting there. This weekend I will flush the coolant lines to and from the block to clean it before putting the thermostat back in. Will flush the radiator, too.

Masis Geplaatst January 24, 2020 Rapporteren Share Geplaatst January 24, 2020 I would replace that metal pipe coming from the waterpump as well. Those are famous to rust from inside, and that rust will get everywhere in the cooling system. You won't put a new thermostat and radiator now you have everything open?

I might do that the next time I change my water pump. I just changed it last July so it may be a while. I hope the rust inhibitor in the coolant can keep it clean until then. I also changed my thermostat last July so I'm reusing it for now. I used to have the higher temp one (195F) since I lived in Alaska, but I now have the 190F thermostat. As for the radiator, I am going to replace it soon. I think it's my next purchase. I have to stagger my purchases so my wife doesn't get too suspicious; she already thinks I'm spending more on the Jeep than on her (and she might be right 🤫).

AK47 Geplaatst January 26, 2020 Auteur Rapporteren Share Geplaatst January 26, 2020 I checked my logbook again and it looks like I was using a 205F thermostat in Alaska and now I'm back to 195F. Today I flushed the coolant/heater core lines, reinstalled the A/C, power steering, fan, fan belt, radiator, A/C condenser, hoses, and the front metal brackets. I have to get coolant so I can start the thing. But I also have to repair the stripped oil pan drain before I put oil in tomorrow. I hope this thing runs. My neighbor has a stroboscope that he can lend me to check the timing (I'm still not sure if I set the distributor right). Citeren Link naar opmerking Deel via andere websites More sharing options...

AK47 Geplaatst January 29, 2020 Auteur Rapporteren Share Geplaatst January 29, 2020 Tapped a new drain hole (13mm) for the oil pan. It was too stripped. Now I can add oil and start the xj for the first time with the new cam. Just waiting for the rain to stop. Citeren Link naar opmerking Deel via andere websites More sharing options...
stephan Geplaatst January 29, 2020 Rapporteren Share Geplaatst January 29, 2020 A litlle tip, you'll already know perhaps, leak a small amount of oil out the drain hole first to get metal parts out the carter before you replace your stop..

Hi @stephan. Yes, I was actually thinking about doing that. And then it continued to rain, so maybe tomorrow I can add fluids and leak a bit out the drain. BTW, what oil filter do you use? I have two of my Fram PH16 left and I have to change oil soon after cam break-in. Maybe I will just take the box to the parts store and see what they have. It cannot be too strange.

AK47 Geplaatst January 30, 2020 Auteur Rapporteren Share Geplaatst January 30, 2020 Ok. Bad news. I tried to start the xj this afternoon but no luck. There is fuel in the rail (I checked at the fuel relief valve and fuel squirted out). I think there is spark (smoke coming out of throttle body). It cranks but doesn't start. Maybe the distributor is out ot timing? (I wasn't sure if I did it right but thought it would start anyway). Maybe I'm not grounded right? (I moved the ground connection from the rear of the head to the intake manifold; I have since moved it back) Maybe some electrical connections are wet. (It rained for several days). So here's what I did: 1)I took my compressor and blew air into all the electrical connections that I disconnected and put them back together. I hope I blew all the water out. 2)I also relocated the ground strap back to the rear of the cylinder head. 3)Then I cleaned and tightened the ground at the base of the oil dipstick when I noticed that the nut was loose when I wiggled it. 4)I also put the battery on my trickle charger even though my voltmeter read 12.4 V on it and it cranked just fine. 5)I bought a can of starting fluid to spray in the throttle body if nothing else helps. But maybe this is not so good an idea with the new cam still needing to be broken in? I'll try again tomorrow. Any ideas? Citeren Link naar opmerking Deel via andere websites More sharing options...
Ab Geplaatst January 31, 2020 Rapporteren Share Geplaatst January 31, 2020 Fuel, spark, air, that's all you need. Check and re-chek.... Does it spark? Is the timing right? There's fuel in the rail, butt do the injectors work? Citeren Link naar opmerking Deel via andere websites More sharing options...

AK47 Geplaatst January 31, 2020 Auteur Rapporteren Share Geplaatst January 31, 2020 I checked fuel. I checked compression. I'm missing spark. So now I pulled out the distributor again. How am I to align the rotor to the oil gear slot in the engine the way as described in the FSM? Do I line up the plastic end (red arrow) to point to 5 o'clock? Or do I line up the brass end (yellow arrow) to point to 5 o'clock? And even when I line up the distributor to 5 o'clock, how will the rotor tip (blue arrow) match the 3 o'clock position of the oil gear slot? This is driving me nuts!
