Oil on Cambelt, any danger?

[hmh]

I have oil oozing - either through headgasket or exhaust camshaft seal - and flowing down on the backside of my F4R 732. I loose 20-30 grams of oil after each ride. Some oil got to cambelt inner side. Can cambelt slip because of this? If it does what damage can it do?

it can and will destroy the engine

i bet its coming from the cam seals

the oil can also get on to the back of the crank pulley and may allow it to spin as it does not have a key way.

The engine was recently rebuilt and has new Corteco cam seals. Seals were placed carefully. Does this mean Corteco should be avoided? Any other make you can recommend instead?

wrong seal fitted on the inlet cam?

 

[Fred@BTM]

renault only for the cam seals, i've tried corteco and reinz and had failures with them both!

the 2 cars i've ever had isues with had those parts fitted, NEVER again!

Would I have your opinion at the assembly time, it'd save me time and money now! Thnx.

Took cambelt off, it was leaking from inlet camshaft seal. Extracted the seal and realized it was of wrong size! Dephaser pulley didn't fit into it, instead it was pushing the seal to side of the engine head thus distorting it. Thanks goes to the mechanic who baught Corteco seals for me saying both inlet and exhaust camshaft seals have the same size.

I baught OEM Renault seals, but they were open box. Do they look like good original seals to you? The inprint reads Pa which is Paulstra according to the trader.

I refer you to my earlier post

Seen a fair few like that.

Not had a problem with pattern seals, just wrong ones fitted

I overlooked your earlier post! I think I read it then but didn't realize it may be my case!

Found in my garage the old seals I took off this engine, they look exactly the same as on pic above.
Btw the exhaust seal looks fine, so Corteco is kinda rehabilitated in this case )
