Pinto oil leak HELP!

[s_j]

My 2.1 pinto keeps blowing out the oil filter rubber seal since we changed the oil!?

It has an uprated oil pump but we noticed the sump gasket bolts were loose! so tightened them up, did the oil change and filter and it ran fine for about a day. Then next morning blew the oil seal out an lost 2ltrs of oil on the road

Took off the oil filter cleaned it all up check it, reseated the seal on the filter put it back on, filled with oil and then later on same thing again!!

So yesterday i went back to the place i got the oil filter from and they said they couldnt understand why it would do it and put it down to maybe a dodgy oil filter?

So with a new oil filter put that on, again filled up with MORE oil and tryed it.

It worked great all yesterday and seemed to do the trick, but this morning i got in it to go to work and IT'S HAPPENED AGAIN!!

 

Any ideas!?........

No idea, get another filter from somewhere else and try that.

[evil knievel]

Are you lubricating the seal? And is it the right oil filter? As vista says, try somewhere else. Also try a trusted brand like Fram, if they do filters for Capris.

[s_j]

Yeah a nice smear of oil on the seal before putting it on

It used to have the white motorcraft oil filter on it, dont know if thats any better make?

It has had to different types of filter on it now and both blew the oil seal

[s_j]

Just had a look what filter we used last and it was a black Fram PH2857A Filter

 

Dunno seems like its getting realy high oil pressure when starting, its right at the top of the oil pressure gauge?

[Vista]

That does seem high but these gauges aren't the most accurate, what grade of oil have you used?

[s_j]

several lol 10w 50

 

but just noticed the rocker cover breather was blocked aswell, surley that cant help increase pressures also!?

[Vista]

It won't increase engine oil pressure significantly no but it's certainly not desirable.

 

20w/50 is better suited to pinto applications, the number before the 'W' is the 'cold' viscosity rating of the oil, and the number after the 'W' is the 'hot' viscosity rating.

 

BUT using 20w/50 would actually make your symptoms worse as 20w/50 is thicker than 10w/50 when cold.

 

I'm sorry but it's not something I've come across before, maybe the oil passages elsewhere in your engine are restricted by deposits causing excessive back pressure down at the filter? Try using some oil flush on it.

[s_j]

It is a strange one, i've never known anything like it.

 

Thanks for the help tho

Is it deffo the oil filter and you havn't distorted the sump by over tightening the bolts ?

TBH i have the same problem at the mo on a customers 1.6 pinto (standard) already fixed leaks in the rocker (distorted to buggery), cam seal, fuel pump (no gasket at all just orange sealer) and dizzy (small seal at the top) but it's still leaking from some bloody where and it's driving me mad cos every time i fix a leak and test it for 20 - 30 miles it's dry as a bone, then a week later there's a new leak somewhere else !

Have you checked the breather is clear under the manifold if your still using the standard item ?

[baz105e]

If it were my car i'd give a cosworth oil filter a go (shorter one), smaller capacity filter that should flow a little faster, its got to be worth a shot

also have you checked the thread on the block where the filter screws onto ??? if this is slightly damaged then the filter may worke loose when it gets hot

[w p e]

check the filters got the releif valve built in some cheap one's dont. thios sounds more like the releif valve in the pump stuck so oil pressure get to high and blows the seal. try flushing fluid but dont rev the engine while its in there and see if this clears the sticking valve

[vibrating_Cake]

just for a little idea, im running an uprated pump, but on a zetec (filter fits exactly the same) and the oil pressure far exceeds the guage on the dashboard for oil pressure, as in when cold on tickover it runs just under maximum, when you rev it, obv the pressure rises.

in general when warm the guage jumps up about 3/4 of the scale between 1000-7000rpm, so running nearly double the maximum pressure on the guage aint a problem for the oil filter seals.

 

are the inner threads of the oil filter streight and true??

are the mating faces of the oil filter to the block streight and true, without any kinks etc oil can find their way out of?

 

and is it the filter thats the ONLY place oil leaks from?

 

also, on the *thinks* nearside of the engine block, under the inlet manifold, theres an oil breather there, may be worth checking if this is blocked, but if your oil pressure is still on the guage i shouldnt see a problem whatsoever =).

thanks for all your help guys its all good now been running for a few days without any probs
