hi all;
well, I am about to pull the head and thought i should ask a few questions first.
I have a 76 bonnie, with the four ball plunger pump which i had hoped would sort out wet sumping issues.
it's been resleeved and had the top end done within the last 7000 miles i would guess, but can't find out where i wrote down the milage at the time.
i pulled the sump drain after it sat for the last 5 months of our long Canadian winter, and about 3/4 of a cup of oil came out - which seemed reasonable to me after such a lengthy hold up. it always seems to wet sump a small amount when parked for more than a few days, smokes on the left side when starting, then clears, and starts smoking again once it has really heated up.
i have new bronze guides ready, if needed, but wanted to consider also putting seals on them - despite seeming like i will have to lathe them slightly thinner on top and put in retaining grooves.
also threw a compression guage on one side today and only got 50psi! i had already drained the sump and any oil would have leaked past the rings while it was sitting - but this seems extrordinarily low right?
i pulled the oil pressure release valve domed nut for cleaning, and it seems to work smoothly... at least unless the plunger is supposed to stop on it's way out. seems to have a very slight lip preventing from coming out all the way without pulling the body and letting it out in the direction it usually would go into the engine. this is okay right? it has also never seemed to more than mist oil out of the breather or fill the primary at a noticably fast rate
thanks for any advice and all replies
