Want this question answered?
it's a 16 valve, 2 cambeltdriven camshafts
simply to get more power I "believe" that 1991 was the first year for the 16v. I have a 1990, and mine is an 8 valve. Hope this helps. -Tony
yes both the 8 valve and 16 valve engines are interterence engines
16 valve engine not put in a Tracker till 1996. 1994 Tracker is 8 valve (but a Sidekick may have the 16 valve in 1994) Actually there were 16 valve Trackers before 96. I have an early 95 which is 16v version. I believe 16v engines started somewhere between 91-94. I do know that the valve covers usually state 16 valve when it is. ,the spark plugs in a 16 valve are waaayy down in the top of the engine,you need about a eight inch extention to get at them
The year, make and engine info would be helpful.
it will be an 8 valve engine as all the 16 valve 1.2s have a 16v badge on the door mouldings
phone a vauxhall dealer and give them the reg or chassis number or check the log book
I'm sorry, the 16 valve head will not work on the 8 valve short block. The piston crowns are cut differently so replacement of pistons would be necessary. It is my understanding though, that it COULD be done if the pistons were replaced. I have never attempted this, but by looking through the parts catalog, it seems that this is feasable.
8 Valve code AEH 16 Valve code ATN are listed for the 1.6, 2000 VW Golf
Likely it's a 16 valve. When the Tracker first came out it was 8 valve, but sometime in the early 90s it went up to 16.
The more valves, the more air. The more air, the more fuel, more power.
If it's an 8 valve engine and not the 16 valve: Bosch Spark plugs have a gap of 0.8mm NGK spark plugs need a gap of 0.9mm 16 Valve engines have a 0.9mm gap on each type of spark plug
