hi i hav an 1997 paseo for some reason it seems to be smoking alot when you giv it alot of throttle!!!

e.g say i was at a standstill holdin the revs about 3000 for 5 seconds then gave it a quick (blip on the throttle)

it would send two puffs of black smoke (fuel i thinK?) out the exhaust pipes followed by a light grey smoke afterwards (Oil i think?)

this smoking is very excessive as it has never done this before.

also say i drive the car for a few miles there is always black sooty deposits left all over the rear end!

any ideas would be helpfull...?

it is a 5E-FE engine that has done 60,000 miles

i have checked the fuel presssure regulator it ok , changed the coolant temp sensor , injectors hav been sent away + tested!

cheers guys oli

Hi,

It seems like you've problems with the valves guide (i don't know if it's the exact term in english, sorry for my eng), maybe caused by a neglected valve clearance control ...

The engine burns Oil or the Oil level after, say, 5.000 miles, remain the same ?

I've read you used nos...maybe there's a connection.

You could make a try, to discover if there's a major problem in the engine :

Try to drive in a empty road, with hot engine, reach about 4000 rpm in a high gear (4th-5th), raise the foot, let the revs get down to 2500 about, then give full throttle, if the car smokes, you have a major problem with the engine valves.

otherwise you have to check water, if the level remains the same or your car drinks a lot ;) in this case you have a major problem with the engine head, usually caused by dealing badly the engine when it's cold.

bye :) [sorry again for my english ;) maybe you're laughing :)]

I remember a problem just like this on an old Micra I had. It seems a common problem with the older micras is worn piston rings and this is what caused smoke in that instance. This may be another candidate to add to the list.
