Smoke and fire? Uh no not normal... The LS400 uses an aramid-fibre reinforced timing belt. If you are seeing melting it's possible that your water pump is seizing up and stripping the teeth off the belt. I would have the car towed to a mechanic immediately...if it snaps it can ruin your engine. How many miles does the car have? The belt should be replaced at least every 90,000 miles...

1990LS400 Posted March 13, 2007 Share Posted March 13, 2007 It is doubtful that a breaking timing belt will cause damage on a 91. The jury seems to be out on 95-97 on whether there would be any damage. For sure there will be damage on a 98-up LS. I seem to be one of the few who have actually had a timing belt thown on a gen 1 LS. There was no damage to my 90 LS when it happened and the repair shop owner who fixed it confirmed that damage would be very unlikely on a 90-94 LS.

92Lex Posted March 14, 2007 Share Posted March 14, 2007 It's hard to tell if it's bad or not, unless it's making weird sounds. Quote Link to comment Share on other sites More sharing options...
djspawn00 Posted March 14, 2007 Share Posted March 14, 2007 Are you 100% sure that the burning you're smelling is coming from your engine bay and not a plastic bag stuck under your car? What part of brooklyn are you in, if you're really that uncertain i can recommend an honest mechanic to you that would look at it. Quote Link to comment Share on other sites More sharing options...
