I’ve got a 1994 Daimler XJ40 that is probably only really good as a parts car and I’m about to list it for sale so that someone can make use of it. I’d like to satisfy myself before I list it that there’s nothing wrong with the engine because recently, about 5 to 10 seconds after starting, it’s producing clouds and clouds of acrid white smoke.
I’ve read that this is possibly brake fluid leaking from the master cylinder in to the inlet manifold, but I can’t find a post here that deals specifically with this problem. It seems fairly likely as the problem occurs as the brake system gets pressurised. Short of pulling the fuse for the brake pump, is there a reliable test I can do to verify that this is the problem?
The car doesn’t seem to be losing coolant and it seems to be smoke rather than steam that I’m getting. However, I don’t see that the brake fluid level going down either - I’m working on the theory that a little oil in the combustion chamber creates a lot of smoke.
It’s a bit of a mystery to be honest.
Many thanks for taking the time to read
