 |
|
I removed the head on my '83, but failed to install the cylinder o-rings properly on re-install. quite a mess with coolant everywhere--crankcase, filter, intake manifold! I also cracked one of the cylinder sleeves after pulling both out when removing the head; the o-rings had pinched the sleeves to the head. except for small dings in pistons, there was no other damage.
fortunately, i found a replacement cylinder sleeve and re-installed the sleeves utilizing a 3-5 inch diameter hose clamp. i spent several hours on my back fishing the clamp out after sliding the sleeve over the pistons and rings.
surprisingly, everything got put back together. rocked her back and forth to get all coolant out of the crankcase, mostly bled and tested her on the road, and notice a rattling under load, which doesn't appear under idle (albeit a fast one).
what should i do besides checking all the vacuum lines to smooth out the beast under acceleration/load?
also, thanks for all the help and links. I don't think I would have even tried to undertake this project without all the encouragement and information in this forum.

aint those o rings fun? I put my 1.9 together countless times before I finally figured it all out....the lifters take forever to pump up babes.....
so leave them loose an let it run....forget EPA rules, let the engine run while those lifters pump up, sometimes they will take 1/2 a day....
keep running the rack on the valves, if you get a dead miss, loosen the valve up, let it run with sloppy valves for a while til the lifters decide to pump....then only 1/2 a turn
forget Bentley 2 cranks.,....one max, you get them too tight you get a dead miss....
I used a compression tester on one engine, first try was 30 lbs, then loosened the valve by one turn, got 60 lbs of compression, loosened them up another turn, got 150......
play with timing...
they are rough runners btw, but timing, vacuum lines, make sure the intake is snug, they do come loose off the head, I found WD-40 located some leaks.....
valves, leaks and timing, you are in an area where you can bump the timing up a bit, without worry of smogging issues,,,,,find a spot that that beast likes the timing at,
:fist:
so much for Bentley.....  |
