oil pump housing

[otterstricks]

Howdee fellas,

My 3.18i touring is just back from failing her mot (as expected). She has a serious oil leak and although it wasn't a fail for that reason I don't see any point in adressing the fails until the oil leak is remedied. The leak is due to a gasket breakout from btween the the oil pump housing and the block, round about the where the oil filter housing bolts on.

It's going to be a tough job to replace this gasket as all the componentry at the front of the block need removed, timing, water pump.....etc.

I foresee a real problem being extracting the oil pump housing(OPH) from the block as it is on dowels and needs to be pulled straight forwards. The oil pump housing also sits on top of the upper sump gasket.

I am worried that when I remove the OPH from the block it will tear this sump gasket and give me another enormous problem.

Does anyone out there have experience with this job or any pearls of wisdom to send my way????

thanks guys

I don't have much useful information, but a thought...the sump gaskets are a known problem on the m42 block, I think it's been said that the same problem can occur on the m40...from the wiki it's not difficult to replace these gaskets...may as well do them at the same time and it might make for an easier procedure?

The Filter housing comes off easily, after removing the Alternator, the rubber o-ring & gasket are simple to replace thereafter.

Hi guys thanks for the replies. It's not the filter housing that has the gasket problem it is the oil pump housing that runs off the crank shaft.

cheers
