Tearing Off The Head

[AWD-Wrecker]

The timing belt was snapped in my 92 eagle talon tsi,
its an automatic, and im hoping this saved me as the car seemed to just shut off when it snapped.

I was gonna just slap on a timing belt and hope for the best, but now im rethinking this,
with a $1000 budget, would it be worth it to pull off the head? i dont believe any of the valves were bent, but im told theres maybe a 1% chance i didnt bend any,

also would it be possible to run on slightly bent valves?

I would appreciate some advice

With a snapped timing belt,the chances of bent valves are very high. If your budget is $1k, I would recommend getting the head rebuilt with new valves and get arp headstuds while the head is off & a new head gasket of your choice.

heads arent very expensive. why not just pull it off and see.

are you doing the work yourself or are you paying somebody

where could i get a head/valves

Take off your head and see if your existing head is still useable, just get new valves and check to see if you there are any broken valve guides

Balance shaft belt, water pump, timing belt tensioner, tensioner and idler pulleys, timing belt eccentric tool, cam seals, and valve cover gasket. You'll spend most of your budget to do the job right.

You'll need a good torque wrench and a pretty thorough socket set- if you choose to use ARP studs when assembling the head, you'll need a 12-point socket set to fit the ARP nuts.

Well its taken longer than expected but staill havent hit any problems, head is in the shop but hopefully out soon, then shes goin back on!

Good, just take your time when you put it back together.

Are you ready?

Bring head down to the machine shop. Have them go through it. Basic 3angle valve job with new valve seals will run you about $300-$450 depending whats wrong. Depending what head gasket you run, you will need the head surface prepped correctly. You want a mirror like surface if you want to run a MLS head gasket. I say run a set of ARP head studs w/ a stock composite head gasket. Next, make sure you clean the deck surface on the block and check for flatness.

You should buy a new water pump, timing belt, timing tensioner, timing idler pulley, and depending on what you want to do with your balance shafts, to keep them, I would get a all new balance shaft components or if you want to remove them (which I would do), I would get a BS removal kit. make sure the stub shaft has an oil groove in it or you can look into the AMS style balance shaft kit that doesnt use a stub shaft. To do a balance shaft removal, you need to take off the front case which means pulling both balance shafts, dropping exhaust, tcase, and oil pan.

Next, you should buy all new gaskets like intake, exhaust, valave cover, etc. Use all new seals for the fuel injectors (3 rubber seals an injector)

I am sure I am forgetting small things here and there so if you have any questions, let me know. I covered the basics for you.

Goodluck

the job is all done, i had the head resurfaced but besides that all of the labour was done by myself an a friend, i didnt get the valves machine seated so ill just take it easy on it until they break in. anyone interested in pics of the build?

 

[jrohner]

Good luck on having much compression then. You should've had the head done correctly, instead of trying to save a measly hundred bucks not getting a valve job. I'd do the valve job and skip the head resurface way before doing the opposite.

Did you at least lap the valves with some compound and a drill?

 

[AWD-Wrecker]

actually the compression is fine, it runs and idles fairly well, it will just take some breaking in of the valves before it runs perfect.
