Hello I purchesed this car cheap to fix for my wife. When you crank the engine up it does not smoke untell it warms up and it is very little but it you step on the gas it realy starts rolling out the smoke so i am thinking the head needs rebuilt but wht do you all think?

The engine has 164000 miles on it so I am thinking of rebuilding the hole thing, I am not wanting to build it for high H/P but for gas milage. I have ported out 2 sets of ford 5.0 heads power but would porting out the head on the 2.0 hurt it or help it?

Thanks Jim

Hello,

Your 94 laser is not a 420A powered car. You have a non-turbo 4g63. Your best bet would be to post in the 1g/4g63 forum.

Now which one is it? by this its a 420A http://members.shaw.ca/costall/1000Q/

What does 4G63 mean?
What does 420A mean?

These are engine model designators. 4G63 is the Mitsubishi model number for the DSM turbo engine, which was built entirely by Mitsubishi. The 4G63 model number was used for 1G turbo, 1G non-turbo and 2G turbo engines; although the engines are somewhat different from each other, they retain the same basic design.

Please note that there are different 4G63 engines, although posters on the Talon Digest almost invariably mean the turbo 2.0L version. Generally speaking, components from one 4G63 can be fitted to another 4G63, because the basic components (head, block, etc) are the same.

420A is the model of the Chrysler-made 2G 2.0L non-turbo engine. Fundamentally different from the Mitsu 4G63 engines, the 420A represents a distinct shift in DSM evolution, as Chrysler took over engine duties on the non-turbo cars. Generally, components from 420A engines cannot be fitted to the 4G63 engines, or vice versa

hmm well this is a general engine question I don't don't see why the 420A guys can't answer it, sounds like it could be a lotta things. One thing is what color is the smoke? If its white its most likely your head gasket. if its black it could be rings, headgasket, or valve seals. Do a compression test.

black means its running rich, not burning oil. burning oil is blue

Hello thanks I can never realy tell the diff in white and what people call blue smoke but anyway it looks white to me but i can small the oil and there is not any water in the oil that i can tell it does not look milky but the car has 164000 on I am just going to rebuild it and be done.

Thanks

Jim

On a 1g 4g63 with that many miles, typically it's the valve stem seals that wear out.
