Alright. I found two problems. Whoever put the timing chain on had the wrong marks pointing at each other, and my fuel pressure regulator was bad; 60lbs at the fuel rail. So timing is good now and new pressure regulator, now it has 120lbs of compression and 40lbs in fuel rail. Runs alot...
Ok, so I think that the cam timing was out. I got the two marks to line up and spun the engine over two revolutions and they still line up.
So I am going to put it back together and see how it runs and if it has better compression.
Got the timing cover off. Found out that the previous owner put a dual roller timing chain on it. And the dowel pin that held the cam sproket in place was very loose.
Does anyone have instructions on how to set timing on one of these. Pics would be greatly appreciated.
Sorry. The compression was 60lb right after rebuild. So I drove the truck for a couple of months and did a compression check. 60lbs still. Did a leak down test, everything was good, no air getting past rings, valves, or crankcase. Checked cooling system, exhaust pipe, oil filler hole, and...
The compression is 60lb on all cylinders. As far a the valve lash, I did not know that the valves were adjustable. I already have the engine apart, so I can't do a compression check again. We checked the gauge on another vehicle, and it was showing to be accurate.
I poured water into the...
don't know about the ring gap, my dad who use to build engines for Engine Masters, put the rings and pistons in.
The head looks good, I'm going to have it checked out this week to make sure it's good.
As far as the deck height, I don't know.
I noticed that the stock piston dish and pin...
I bought a 1988 Jeep Comanche about 2 yrs ago. When I first got it, it wasn't running right. So my dad and I put new rings and bearings in it. I drove it for a few months and did a compression check and it said 60 pds on all cylinders. So we thought that the rings didn't seat, so we tore it...
