Head to block oil leak?!? Tighten the HG?
Hi all,
I've always had an oil leak with the 84 so I figured it was time to clean it and investigate. I checked it after 15 miles, 30 miles, then cleaned it again and checked after another 6miles of driving. First 15 it puddled a little on the tranny, mainly wet back there, a little was on the rear passenger side of the block. After 30 miles the tranny was pretty well covered in it, and the side of the block was soaked and probably dripping again. After cleaning it again I see that mainly the whole leak is at the rear of the motor where the block meets the head, some oil also leaks at that same seam around the corner of the motor. Upon inspection with a mirror the turbo feed line seems pretty well like new, everything from there and above is perfectly dry. Any ideas or suggestions? Should I try to tighten the headgasket or will this only create more problems and should be avoided? Thanks.

Well I bought a few each of the different bolts, I suppose I'm going to try to take each one out one at a time and put a new bolt in. A freind of mine suggested that some people use a sealant on the head bolts, is this true? What kind of sealant? While searching on this I read about someone successfully using a Permatex product to form a seal over the leaking area on side of head gasket, should I try this or do you think it would just send the oil somewhere else where I don't want it?

Jeff,
Try using JB Weld. I've had luck with that product sealing a small oil leak where the head and block meet. Herb '82 240D '87 300SDL '92 300D 2.5 Turbo |
