does the sump on a 1991 mi16x4 have a sump seal or does it need just gaskit in a tube sorta thing??

Well, you have the sump AND a plate that sits between that and the block which acts as a stiffener. Sealant is supposed to go between block and stiffener plate and then a cardboard gasket between stiffener and sump. However most people don't use the cardboard gasket and just use sealant instead. A right bitch of a job to do with engine insitu and especially if like me you got the stonking gert aircon compressor attached to sump.

I think gaskets are only to be used on steel sumps. I use ThreeBond 1211 between the mating surfaces. It's absolutely brilliant suff, designed for high stress, metal-metal applications such as motorcycle gearboxes. Perfect for an Mi16 sump.

Parts cd shows it for the Mi16 sump though. I wonder if I can get that ThreeBond stuff over here.

Bearing suppliers usually.

not sure, definitely different stuff.

Hi all, just how do you get to those top bolts attaching the compressor to the sump?

Cheers

Unbolt the A/C hoses that are held on to the block the the block and push them out the way. Then use whatever breaker bar/ratchet/extension combo works.

Definately do-able.
