89 929 139000mi. Over the past couple of years I had a pretty bad burning rubber smell coming from the engine. Eventually I traced it to a timing belt problem (well traced is stretching it, the thing broke), and after a few times changing the belt I finally got it right by replacing everything with Mazda parts. The smell never really went completely away. It's not a acrid eye-stinging stink any more, mostly just a hot rubber smell. I know I am leaking oil at the PVC housing and at the distributor hole blanking plate on the passenger side of the engine. The driver's side VC gasket is also leaking a bit. I change oil every 3~4000 miles and only have to add if I've been pushing the car very hard, 80~90 for a few days. When popping the hood after a hot run to trace the smell I do see a little smoke coming from the back passenger side of the engine. My question, is the rubber burning smell maybe really an oil burning smell. Anyone had similar leaks that smelled more or less like burning rubber? I really don't want to have to disassemble the timing belt area again if I can ovoid it.
Thanks for any info.
