not a good sign?

hello all,

Well, this is my first post on this forum and it's not the happiest of subjects for me to be starting with and I'm hoping that someone here can put my mind at ease.

My 306 seems to have gathered a large quantity of oil in the radiator filler pipe. I can only speculate that somewhere in the system oil has leaked in from the engine. At the time I had no choice but to use the car which ran fine. The oil level has only dropped slightly but I know I need to take the car off the road to get it sorted.

Is there any DIY remedies that I can do or is this a pro job and if so what's the problem I'm actually facing so that I can go in and sound like I know what I'm on about.

cheers

 

Oil in the coolant is usually a sign of serious bad news. It could be from several faults; 1. blown head gasket, 2. warped cylinder head, 3. cracked engine block, et.al. Have you overheated your engine recently? I would pull the plugs and see if there is one which looks substantially different from the others. Looking on the underside of the oil filler cap do you see any sign of moisture (white frothy crud). Is there any water on your dipstick? You will probably have to pull the heads at the least to diagnose the problem. Driving will only make the issue worse.

 

cheers for that thiggy. I managed to speak to a couple of other people and they've said pretty much the same thing. I've checked the oil cap and dipstick and all that's there is oil, no sign of water at all, so I'm hoping the job isn't has bad as it could have been.

cheers

 

Those items which I mentioned are probably the most likely cause of oil in your coolant, but not the only possibility. A few years ago my son had the same problem (oil in H2o). In the course of removing the cylinder head, we had to remove the timing chain cover. We discovered the timing chain idler had worn to the point that the chain was slapping the water pump housing. It had worn a hole through to a water chamber and thus was allowing coolant to flow into the oil, and vise versa.

 

You'll have to get a couple quotes to fix these unless you're an skilled mechanic or DIY'er, work will involve taking cylinder heads out, replacing all gaskets, have heads fixed at a shop or put new ones on,replacing timing belt,flushing radiator and all cooling system.
Also consider getting a rebuilt engine with core exchange they're not too expensive if you install it or have your mechanic install it.

 

Perhaps the transmission cooler circuit is leaking fluid into the coolant? Check the transmission fluid for milkiness.

 

Well i should be having someone look at it tomorrow so I'll know what the problem is for sure.

I'll keep you all posted.

Cheers guys
