Spin-on filter

Post by **les** » Sat Oct 26, 2002 8:48 pm

Hello,
I could well be the last person here to do this conversion, ie: change from paper element to spin-on filter, however I've got the housing ,gasket and filter but can't, as yet, find the shorter studs that screw into the block to hold the housing, the next plan is to make a couple but would like to know the length that protrudes from the block, my guess is about an inch. Can someone tell me for sure? Thanks.

Lo Les, well on my set up,which is off of a Mini,
the studs protrude 1 1/4" from the block face.
The last 3/8" of the thread is superfluous. The
important thing is to ensure that the part of the stud
which passes through the flange is as good a fit(NOT
threaded) as possible as I find I get a slight weep of
oil from there despite a good gasket

Thanks Willie, I'm going to cut down and re-thread the original 'long' studs so will work on 1 1/4'' from block, I have noticed the new gasket is not as substantial as the original, a lot narrower around the outside, I usually use a smear of silicon on gaskets, with good results. Gasket for housing £1.50 can you believe it!

I always use non setting Red Hermetite on my gaskets ( i made
this one out of a Kellogs Corn Flakes packet)!!

Just a quick question,

I usually use the blue gasket compound, what is the difference between the red and the blue? (apart from the colour!!!

)

Lo, in the Hermetite range of gasket cements the RED indicates
a cement which does not set hard. Their other type is brown,
and it does set hard(i.e. you will never separate a joint without
ripping the gasket). I think your 'blue' one is made by 'Hylomar'
or something similar. You stick to the one which suits you.

I've always taken the Red goo to be the set hard one,didn't realise there was Brown, the Blue one is none hardening and feels more 'sticky' IMO.
I started using the White silicon type after the local Austin/Rover dealer said that they were getting too many cars returned to the workshop with oil leaks after having work done on them when using other types of gasket sealant, I wonder! I will say, it seals well.

Cheers for the info, Willie.

Les, I have had problems with previous owners / repairers using clear silicone, which is why I started to use the blue sealant.

It has mostly been OK but I have had a slight leak around the fuel pump take off on the side of the block when I blanked it off.

I don't know if this was the sealant's fault or there was some other reason (uneven surfaces - too high pressure etc.)

It is not a serious leak so I have not bothered with it. (more serious problems elsewhere!!!).
