Smoking when hot

[petery]

Hi

Bought a chimaera 500 on Monday, I've done 300 miles in it and now when its hot it is smoking badly with blue oil smoke. Has anyone else had this or know what it could be?
The car has done 49000 miles and been very well looked after.

could be oil from the diff overflow dripping onto the exhaust?

[petery]

definitely coming from the engine (out of the exhausts)

id do a compression test ASAP, could be worn piston rings, damaged liner, a head gasket, or valve stem seals.

is there any sludge in your coolant?

Also....
If you have PAS check the exhaust pipe were it runs underneath the PAS pump. The U pipe on the pump can leak and drip PAS fluid onto the joint that finds it's way into the exhaust and creates lots of smoke although mine was mostly white smoke.

I think compression test is the next thing, My feeling is that its rings but i'm not sure. Its fine when cold and not a trace of smoke its only once it get warm. It all sounds fine, it hasn't been driven since i noticed it so hopefully damage is limited.

has it got the correct grade of oil in it?
have you spoken to the last owner about it?

It has the right oil in I have a bit for topping it up, spoke to the last owner and its not something he has ever had a problem with

how did i know he would say that!
wip the plugs out and check their condition should tell you where to start looking,
could be head gasket leaking oil into the combustion chamber, you don't need a lot of oil to create a lot of smoke

Interesting, I think mine did exactly this yesterday, is diff overflow from the breather common then?

assuming the breathing is OEM, worth just making sure the little mushroom breather on the back of the near side rocker cover is clear... it has a hole maybe 1.5 or 2mm or so right through into the rocker box, under the foam filter that sits atop. This is critical to the engine breathing and if obstructed with rust or whatever, the car will suck oil fumes through the intake and puff smoke

PS Dont believe anyone who tells you there is a valve in there

I think the BTR diff is prone to it, mine did it alot after it was refilled to the correct level. I added an extension pipe to the breather and not been a problem since. There is a thread somewhere with pics.

I will investigate that thread
