GasMan Posted August 10, 2019 Share Posted August 10, 2019 I have a persistent oil leak from this junction I have resealed this several times with liquid gasket and each time it comes back after a relatively short time. The cap head bolts are fine haven't pulled a thread. Anyone had a similar problem? recommended solutions? Link to comment Share on other sites More sharing options...

GasMan Posted August 10, 2019 Author Share Posted August 10, 2019 Yes it's where the swirl tower top plate meets the bell housing on the right hand side that it weeps. Dave I hadn't thought to suspect hairline cracks in the bell housing. Will inspect closely tomorrow. Thanks,Matthew Link to comment Share on other sites More sharing options...

SM25T Posted August 11, 2019 Share Posted August 11, 2019 Anthony ... is that where we were looking on your car ? Link to comment Share on other sites More sharing options...
anthonym Posted August 13, 2019 Share Posted August 13, 2019 I don’t think so no, it was the block. Here is the pic you took: I thought the swirl tower was the top bit of the dry sump tower, which is integrated into the bell housing, hence the crappy clutch release arm aiui. But maybe the swirl tower is the whole tank, and the base means the blue plate, which is an old world of pain - like when mine fell off and I lost all the oil.. old story :-)edit: the blue base plate had issues with its gasket, iirc there is a tiny channel for said gasket and oil seeps were common. The bolts are small and themselves would suffer seeping oil, but it’s yonks ago and hard to remember. Memory is saying the bolts are an odd M7 size (try helicoiling that) which is Citroen.. as it happened I was in France. Link to comment Share on other sites More sharing options...
