I seem to have gotten an even worse oil leak since I changed my exhaust mani on my Laser. My manifold was cracked and had several mismatched bolts mixed in with the studs, so I swapped it all out and threw in new studs. I've always had a bit of an oil leak, but only enough to make a mess but the level would never go down, but it's much worse now.
I read somewhere that one (maybe more idk) exhaust manifold studs back into an oil passage and that they can leak profusely if incorrectly installed. I had brake cleaned and blown out all the stud holes then turned the new studs in with a bit of high temp RTV on the threads. Was this wrong, I found a thread somewhere where this was suggested.
My next idea if I can't make an improvement on my leak was to possibly epoxy (JB Weld) the studs in place. This is definitely a last ditch effort if I can't find a different answer
RESOLVED!!
Didn't quite make it to JB'ing the studs into the head luckily, as it would have been in vain. It turns out that while changing an exhaust manifold on a 22 year old motor (which has been apart at some time before my ownership) the slight jostling of the turbo is enough to make a stress crack in the turbo oil return line. I found this by just taking things apart to clean, inspect and reseal, then "Ah hah! this looks like its shifted lately!" so temporary fix will be to saw out the accordion section where it was cracked, and using a section of emissions hose to hopefully get me by till I receive a new one in the mail.
