smell of toast occasionally, and running rich at start up.

[nickeboy 0]

i have a 93 vr6, for a long time now it has occasionally had a funny smell, it is not always there and comes and goes, always when it is warm or hot, it smells a little like burning toast maybe a little sweeter, it seems a little worst recently.

my guess is there could be some oil burning somewhere or the cat?

 

the other thing is it has the faint smell of fuel at startup sometimes and recently is running rich at start up as-well, what tis the preferred order to track down the culprit,

 

many thanks

I'd check the fuel lines and pull on them to simultate engine movement - replace if you don't know the history.

 

The toast smell means you are having a stroke :)

I had a stroke this morning, and I didn't smell toast. I was sniffing your old pants though Steve. :luvlove:

 

Check the pcv valve/rocker cover breather pipe for damage and oil dripping onto the exhaust heat shield. You will probably see some discolouration on it if there has been anything dripping.
