Cold start rattle 2-3 seconds then gone.

my alternator(bosch) didn't want to fit on the new housing so I had to do go through some anger and filing/sanding.

Did you pull the special round nut at the rear of the alt out (rearward) couple mm before trying to install it on the OFH? I pulled it rearward before trying to remove the alt from car every time.

Edited: not round nut but it can slide inside that hex shape hole.

Typo on my part. Instructional videos showed removing the fan for the OFH. I didn't find it necessary, and didn't think removing it would have made anything any easier.

Isn't it easier to remove the belt, tensioner and idler with the clutch fan removed?

How do you remove the belt off the tensioner/idler with the fan installed?

Just completed the OFH replacement this weekend. Can confirm, no need to remove the clutch fan. I don't like removing it if I don't have to because it risks bumping the radiator, and I generally find re-installing it along with the shroud to be mildly cumbersome. Belt drive and alternator assembly is no problem with the right extensions.

The real PITA is that drive side air duct portion of the fan shroud that the upper radiator hose feeds through. One day I'm going to lose it and set the thing on fire. Also, my alternator(bosch) didn't want to fit on the new housing so I had to do go through some anger and filing/sanding.

Install process aside, my lagging oil light on cold startup seems to be solved. So I guess per the points in this thread this remedy was correct. Sorry this doesn't help your case, Andratch

Agree that no need to remove fan for changing oil filter, but removing the fan makes it easy to unbolt the OFH.

In a lot of the instructional videos for replacing the oil filter, they took off the fan and fan clutch (as an assembly) to get more space, but I found it to be an unnecessary step.

Update - I sent my car over to a local indy shop to investigate this today. I'll let y'all know what they find.

Clutch fan? Why didn't -- the nut is too tight?
It took me 5sec to knock the nut loose and remove it using a crescent wrench and small hammer. Don't tighten too tight, just snug then you can knock it loose even with a screwdriver handle.

That said, the oil filter housing did NOT fix my issue, so the whole thing is an unnecessary step!

That's at "operating temp" though, if it makes a difference.

Oil temperature definitely will alter pressure. When cold it will be higher.

Anyone try doing an oil pressure test? Not sure what spec to look for at first start though

Got the old oil filter housing out today, did not need to take off the fan..

3 seconds does seem longer than usual. That is how long my light stays on right after an oil change.

This is the worst case with an empty filter cartridge to fill, and 3 sec is long compared to normally should be less than 2sec.

Agreed. Mine was off almost instantly, even right after I put in the new oil filter housing.
