Talk about going round in circles LOL.
3 rocker arms and 3 pushrods sent out today mate. i'll let you know the postage cost when i do next week.
Right, I finally managed to get some work done on the car today.
I found that all the pushrods were chewed up from rubbing against the valve guides.
Also many of the rocker arms were rattling loose, and some of the pushrods were not seated in the lifters they had jumped out.
So they were all removed, a mate came over and helped me and we stripped off the rocker arms
and pushrods and fitted the new hardened +100 pushrods and refitted the original 1.5 ratio rocker arms, plus the one I was sent by mygasser.
They were all done following the
1 - 8 - 4 - 3
6 - 5 - 7 - 2
when piston 1 exhaust and valve rods are at rocking point piston 6 rods and rocker arms were adjusted etc...
then when that was all done, we did the compression test with the results as follows:
Piston 1 = 130
Piston 2 = 140
Piston 3 = 130
Piston 4 = 135
Piston 5 = 160
Piston 6 = 130
Piston 7 = 140
Piston 8 = 120
So some degree of variation there, but a mechanic told me that with the age of engine I have thats pretty good and it will still run fine.
Finally we fire it up and tested it. The timing was slightly advanced from what it was previously, and was pinking on a test run, so we retarded it slightly,
at three quarter throttle it started pinking again, so we retarded it a tiny bit more. It still doesnt have the same power that it once did, but it is much much better than it was.
I have to admit that the vast majority of the work was done by my mate, I would never have managed it without his help.
The next thing to do it an oil change and flush the engine then put new oil in and the zink engine break in additive that I was sent by comp cams.
I tried to fit the rev counter, but I had bought a dash mounted one and not a surface mounted one and the wires were not long enough to reach, so that is a job for another time now...
The compression test was run dry on a cold engine and the engine was turned over twice for each cylinder, with the throttle left untouched.
I thought I should mention that as I've read different things about putting oil in the cylinders for a wet test and running the test with the engine warmed up and that you are supposed to turn the engine over 4 times for each cylinder. I didnt know any of that when I ran the test. So that might effect my readings?
