Have 2002 ford zx2. It's 2.0 When car runs for five minutes runs great then lifters start clattering an smokes bad..what causes this..


not good . Check exhaust pipe when cold is it blowing out oil put a piece of paper near exhaust pipe check if oil spraying out.

if it is it could be worn rings in engine
or a cracked block
Hard to fix as engine has to be removed and the block remachined or welded. Same with rings engine has to be pulled apart . $$$$$$
You need to get a mechanic to give you an idea on possible cause and possible cost to fix compared to the cost of another engine like a Reconditioned engine or another car.

Engine fumes leaking into car compartment through the ventilation system - how can I fix this problem ?


The main thing you will need to do is to minimise the amount of 'excessive' engine fumes being generated in your engine compartment which in turn will 'leak' into your car compartment: 1) Degrease your engine and check for leaking oil gaskets especially around the oil refill area: oil leaks at the back of the engine falling on your hot exhaust pipes and on your engine block will generate lots and lots of 'nasty' smelling fumes! 2) Check that your exhaust pipes joints are well sealed especially the one contained within the engine compartment: taking great precautions, check for the obvious leaks from smoke emitted but you could use soapy water to assist. 3) Check that the lining in your engine compartment are in good condition taking particular attention to the 'Firewall' ones (e.g. the one between the engine compartment and the passenger side compartment). 4) Check for broken heating/cooling air hoses leading into the passenger compartment.
Hope it helps!
