Engine Mechanical problem
1985 Dodge Truck Four Wheel Drive Manual 125000 miles
I bought a short block and rebuilt head from the Internet. Most of the problem have come from the head.
Here is the problem, after it warms up and you shut it off, it smokes when first stater. I thought it was the valve stems seals. I started replacing them. Prior to I had done a compresion test and one cylinder was 160# and the rest were 190#. Also checked the cooling system with a Fabro leak check fluid. The color of the fluid chsnged a little but not yellow.
So when I applied air preasure through the spark plug hole to hold the valve closed. I started hereing air come out the radiator cap and anti freze pouring out. Got the same results on both # 2 & # 3 cylinders. Thias is never a good thing.
However the first valve stem seal I changed had a hole that was.0025 bigger. That could cause it to smoke right? I an trying a block sealer now, and is curing.
What else was wrong with this alleged rebuilt head. It had 3 striped out holes on the exhaust, ripped o-ring on a jet valve, when the cam gear was removed to attach to timing chain, the end of the cam had been rotated with a pipe wrench and left metal shavings. They gave me a long cam shaft (for front wheel drive) and the camshaft hole threads stripped out (had to remove the lock washer to get a little bite and usre J B Weld and glued the sucker in). My last question, if the block sealer works should I go back and replace the rest of the valve stem seals?
have the same problem?
