'83.5 1.9L westy.
Compression check reads 120 lbs. on all cylinders. I tried to do a leak down test, but I'm not sure I was doing it correctly. I ended up pulling the rocker assembly and the intake manifold off of #1 & #2 cylinders. Filled with 100 lbs. of air, but had a constant leak from both cylinders. I placed my fingers inside of the intake ports touching the back side of the intake valves, but was unable to feel any air. I'm guessing for some reason my exhaust valves aren't closed, or I have a cracked head. Is there a better way to do a leak down test? Every time I filled the cylinder with air, it forced the piston to bdc. Am I supposed to test at tdc or bdc?
I also made a pressure cap to test my coolant system. It seems to have a slow leak, but I was unable to locate a visible source. I made the cap by drilling a hole in the center of the cap and removing the guts. I pulled a standard wheel rim rubber fill valve through the hole, and filled the overflow port with a screw and jb weld. Worked great.
If you could cc me with your response, that would great, as I am on digest mode. Thanks.
