Hey guys, just bought a T25 today, my first one!!!

Its a 1985 1.6TD

Engine has a problem with over fueling. Its a little smokey on idle (not to excessive tho) however when the boost comes on all i get is black reak out the exhaust??

I think it mite be the injectors or the pump??

Anyone any ideas?????

first check the injection pump timing. pump is driven by cam belt and timing only needs to be one tooth out and this would cause the problem you describe. If timing o.k. may be worth fuel additve to try to clean injectors out or may be worth having injectors tested. try these first easiest and cheapest options.

someone will have turned the fuel up to make it go better or the air filters blocked

Thanx folks, air filter is off the van. I thought about the punp being wound open, didnt think about the timing tho!!

will check it out today and let u know how i get on!!
