Good question, I meant to comment on this. Smoke is predominately from the left side. I noticed that both exhausts join in a common...
I should add, I did rule-out one possible cause: the oil/vapor separator circuit. I disconnected the vapor-return lines to the intake manifolds;...
Problem has gotten substantially worse in the last 3 days. Car is now undriveable, billowing amounts of grey smoke begin about 5 seconds after...
Great suggestions, thanks for the many tips. Car is driven regularly (almost daily), garaged. Drives are long enough to get up to temperature...
Trying to diagnose a possible problem with the 2000 456M. Recently (last week or so), on startup, there's a considerable amount of white smoke on...
I've been unable to locate a source for 456 (or 456M) wiring diagrams. Anyone have a suggestion? I'm happy to pay for either paper or...
That's the "M" engine. Under the hump is a heat exchanger that cools the fuel lines using the air conditioning freon. A unique idea, but...
No, I didn't. Only warning was sluggish performance followed by the clutch falling to the floor. It's been a while since I owned the TR, I don't...
I would guess the bonnet is lifting slightly at speed, triggering your sensor. I haven't checked on my 456 and what type of switch, but you could...
Just to add data for the OP. My 88.5 TR suffered from an engine fire back in 1998. Cause was a faulty fuel-pressure regulator in the Bosch...
EXTREMELY common problem on the Diablos. The low-pressure cutoff switch has failed. In fact, this component eventually fails on all Lambos,...
I disagree with this. I've driven both, own a 456, have owned about a dozen other exotics (Diablos, countach, TR, etc.) and frankly, the handling...
I've owned 2 Diablos, a 94 VT and an 01 6.0 as well as an 88.5 TR. Guess which one burned up with a cat fire due to a broken fuel pressure...
Ummm, thanks for that detailed and remarkably lucid analysis. The drivetrains in these cars are essentially the same, with the exception of...
Any advice on removing the center console on a 456 to facilitate a radio install? If someone has done this and can offer a few quick tips, I'd...
No spec in the factory manual for any threadlock; stock assembly had none. Volvo factory manual specs blue threadlock. This is not a...
The steering inner tie-rod on my 456 MGTA was unacceptably worn (about 1" of play in the tire outer edge). I documented a fairly straight-forward...
While changing the tires on my 456 (2000 MGTA), I noticed a large amount of "slop" in the steering linkage, nearly 1" at the tire edge. This...
Perhaps you asked the wrong question initially? I thought the issue was how to clear a check engine light? Easy answer, given several times....
Ok, I'll ask the stupid question in the room. How do you match RPM prior to a manual shift with a slush box? Surely you don't mean to shift to...
