Timing chain

[Boogieman142]

Hello, I am going to change my timing chains and just wanted to see if anyone in here has done it on the 1.6 and to see what I will need to do it. What I have so far is:
upper and lower timing chains
upper and lower tensioners
lower chain guides
valve cover gasket
exhaust manifold gasket
timing chain cover kit (cover gasket and crank seal)
thermostat
oil pan gasket
cylinder head gasket
coolant
oil
head bolts

I just wanted to see if there is anything else that I would need to do it. I am going to do a compression test on the engine before i change the chain to see if there is a diference between normal valve timing and late valve timing.

What size engine? is it a GA16DE

1. need
2. *replace if worn
3. *replace if worn
4. probly need
5. if you want to replace it
6. need
7. need
8. need
9. need
10. probably a good idea


compression probably wont change if you change timing a little, because of overlap. however, if compression is affected, timing will probably be off enough to possibly damage valves or something.

before you take the engine apart, put cylinder #1 at TDC of compression stroke
before you put everything back together, double, triple, quadruple check the valve timing(especially that cylinder #1 is at TDC of the compression stroke, and valvetrain is on the beginning of the intake stroke.)

after you check and check everything, have someone else check it.
putting the engine together with the valve timing off will probably bend valves, and then you have to take your head in to a machine shop and get a valve job and new valves. its not fun.

Yeah I know that it needs all of that stuff, I just wanted if there was anything else that I should do while its apart. The chains themselves are in good shape its just those cheap nylon tensioners that are gone but I am going to just replace everthing while i'm in there. I know how to do it, I've done iton many other vehicles. I am just going to pull the engine and trans and do it with it out of the car so that everythings not in the way. Yes it is the stock 1.6

theres a couple of things that it doesn't need but i am going to replace anyway. These I don't need but want to do:

timing chain cover kit (cover gasket and crank seal)
thermostat
cylinder head gasket
head bolts

u can change the tensioner w/o pulling the tranny with it-its easy the part that gave me a hard time was the T/Housing the rest is gravy
