Pinto spraying oil from top of the engine. STILL DOING IT!

[paul capri]

You may have seen in the general section that im starting to loose enthusiam with my capri now, but I've decided to try and get her fully sorted out and fit my brake kit and new wheels to restore my love with her! But this is one of my main problems at the moment...

 

okay I bought my current pinto lump as a new reconditioned engine about 8'000 miles ago. It was always fine but after a few thousand miles of driving the car, it would spray a mist of oil from the top of the engine at high rpm, which covers underneath the bonnet and ruins the clean engine bay.

 

Then about 3000 miles ago I fitted a ported & polished cylinder head with brand new EVERYTHING and a kent cam. I also put on a larger twin choke weber carb. I thought the oil may have leaked from the rocker cover originally so I bought a brand new one and made a very good job of fitting it, however the problem is just as bad, maybe a little worse since the engine will rev harder.

 

The compression is absolutely fine, the other thing I tried was fitting a breather cap with an outlet and running it to an oil catch tank because it looked like the oil may have been coming from the cap, but this didnt stop it either, it did exactly the same thing as when it had a normal cap.

 

The breather itself which fits to the engine block is fine, the pipes aren't blocked and the one way valve works fine.

 

The oil always seems to sit on the left side of the rocker cover, but the right side is always dry and free from oil. When looking at the pinto in my mates capri, it looks like it does the same thing as mine does!

 

Any help would be much appriciated!!!

Mine did this for a long time - trust me its the breather - take out the one way valve and stuff a fat tube in there and run it into a dr pepper bottle or summat and hey presto

[SmokeEm]

Happens on mine too. We junked the valve from the block, fitted a sleeve from ebay, a transit filler cap and routed both hoses into a catch tank with a breather on it. Job's a goodun

Its the breather/flametrap below the intake manifold. The oneway valve is probably stuck.

[paul capri]

okay cheers guys, Ill give that a go, but where exactly from the engine does the oil come from then?

[caprinerd]

think the majority of us have had this at one time or another as already stated the one way valve from the crankcase (under the inlet manifold) sticks open,take it out clean it with parafin or simular or just run an open pipesystem to a catch tank (beer can or something like that) and empty it when it fills (it takes a while to fill)

[Trevmk3]

think mine might be doing that aswell as leaking so i will have to have a gander

[Superblue76]

Mine was also doing this, I just put a baffle plate in my rocker cover just under the filler neck. Completely stopped the oil spraying out. I was told it was because I was running a high pressure oil pump

[paul capri]

okay I tried putting a pipe straight from the breather hole in the engine block straight to a bottle to by-passes the one way valve. I also used a transit oil cap with an outlet run to another bottle aswell. Both bottles had breather holes.

 

I took it for a good run, used about 10 quid of fuel, I stopped, pulled the bonnet catch, crossed my fingers and opened it (after having cleaned everything).... oil everywhere

 

sometimes I just feel like ringing the local breakers yard and telling them to come and pick it up.

i have a normal cap on mine, still gets oil on the rocker cover though but not a lot, i have a spare if you want

[paul capri]

what sort of RPM do you take your pinto up to? I don't think they do what mine does unless your really giving them some abuse. (not beyond what the engine components are capable of withstanding of course!)

[Copey]

it goes to about 6.5 but very rarely

[paul capri]

anymore ideas guys?

[SmokeEm]

You sure it's not blowing out the dipstick tube - ours does

[paul capri]

I thought it might have been this aswell, so I removed it and refitted it after having tinned some solder on the end, hammered the b***** in nice and tight so it cant be coming from there.

[Copey]

have you tried a different rocker cover?

[bortaf]

Have you checked the cam seal? though TBH it looks too far back on the engine to be that

[paul capri]

yeah i thought it might be the cam seal but its only 3000 miles old and like you say the oil looks too far back.

 

The rocker cover is the second one ive tried, it was brand new when I fitted it so its not all bent out of shape from being pulled of multiple times, I used a new gasket and the best part of a whole tube of loctite rocker cover gasket sealant!
