I had to throw out my car manual the other day since i had a leak in the trunk n it got ruined.

I just need to know what side is 1-2-3 n 4-5-6.

I THINK 1-2-3 is on the passenger side n 4-5-6 is on the driver?


2.8 v6

 

My 3.1 is 1,3,5 on the pass side and 2,4,6 on the driver's side.

If it's your origional engine, it should be a 3.1 in 1990.

 

whichever cylinder head is farther forward on the block than the other is where your #1 cylinder is located

this applies to all engines


aso, if you look on the intake runners the cylinder numbers are cast on them near the valve covers, large raised numbers

 

#1 is front passenger side.

 

wut that be the same for the 2.8??

 

Should be for our cars. I'm not sure about real early 2.8's.

Either way if you put a 2.8 in yours, yes it's the same. Is your's the origional motor? If so it's a 3.1.

 

In a few days i'll scan my haynes book. It has a drawing of it.

 

Nah it's a 2.8 from an 89 RS.

 

Same firing order as 3.1s. #1 is the front passenger cly and #2 is the first cyl on the driver side.

 

Pictures are easier to understand.
Here ya go.

 

I found my haynes book, Its firebird not camaro. if needed I'll post the info in it. Otherwise i'm outta the topic.
