Re: Oil leak and poor idle

The carrier that the coil packs live in is plugged (coaxial with the camshaft) into the side of the cylinder head. The plug is sealed with a rubber O ring, if there is lots of oil under the carrier casting the o ring may need replacing.

When you get the carrier out, clean out the hole & apply lots of clean engine oil distribute it well, with a clean rag & then degrease the carrier spigot, replace the o ring and apply a continuous bead of RTV next to the o ring, replace the carrier.

It might not leak, without the RTV.

The coil packs slot in where the distributor once was, there is an O ring behind it. Fit a new one.

Check for induction leaks. Your car should be MPi so can have the diagnostics done.

rtv is a silicone type sealant.

With a new O ring it should not be needed.

Replace any split pipes, things move around in the engine bay under load.

Re: Oil leak and poor idle

Hi

David is correct you should not need sealant with a new o ring, but this is a Fiat ... if the old ring has cuts or splits the castings may have rough edges, and the sealant will fix any bad symptoms, it would not be good if it gets into the oil passages.

If it is leaking it may be because the crank case and cam shaft area is pressurised. It is desirable that all the pipe-work is intact and clean of any gum. I recommend replacing compromised pipes.

The wee cars go ok when they work.
