    thank you so much do you know how i can get a diagram picture with the precise instructions so i can double check my work

  • twinkle616 May 15, 2009

    i had to replace the head gasket because it was bad i had the haynes book and i followed the directions to put car back 2gether when i put the timing chain on it looked exactly like the picture in the book the only other thing that i thought was strange is there were no markings on the engine block to match up

    I just checked a CHILTON'S manual and for the '88 - '92 and for the Q45 it references silver and gold mating marks. If you still have the old chain you removed, you may check to see if you can see the marks.

    Since you remove the head the chances are the camshaft and crankshaft are not synchronized. You can check this by removing the cover on the pulleys and see how much off the chain is. You can try putting the chain on correct and see how the engine run. If it does not start, you have bent valves and you are not getting compression. That's the bad news.

    The good news is you can get the head rebuilt. Several of the valves will need to be replaced and probably all valves seats reground with new oil seals. Information I got from an engine re-builder is when part of a modern engine is rebuilt it will eventually cause another part to fail. The engine is probably designed to degrade together.

    I always use the factory service manual for repairs. You can get a factory manual from eBay or the internet. Some auto parts store sales agents can sometimes help since they have heard just about everything.

  • marionbagget May 11, 2010

    I believe this is an interference engine so if the crankshaft and camshaft are not synchronize, the valves could hit the pistons and bend. This should be checked. If the chain is off by a tooth on the sprocket it may not have bent anything, but this should be checked to see if it needs correcting.

    The mark on the camshaft or crankshaft could be an indentation, paint mark or bump on one of the teeth.

  • marionbagget May 11, 2010

    Did you verify that the crankshaft pulley and camshaft pulley were aligned with the proper marks on the engine block after the new chain was installed ?

What the last person said with the additional comment that being even one tooth off can cause it to run bad or not start. I prefer making marks on the gears and chain or belt- whichever you have and transferring the marks by teeth counting to the new belt or chain- fool proof. Did you rotate either the camshaft or crankshaft with the timing chain removed? If your engine is not a zero interference engine than you may have damaged the internal parts. Even on some zero interference engines, you can damage the camshaft by rotating it backwards. Your timing is just plain off or you may have damaged the engine. Sorry, don't know if your is a zero interference or not- I think most are not. I know my Miata is and my Eclipse was not. If it is not a zero interference engine and your marks are way off on your timing- just go ahead and save up at least the money for a new head and send it to mechanic. If it is a zero, and your marks look on- see if the interpretation of the mark could possibly be 1 tooth over on either the cam or crank. Make you go blind staring at it that intently and u can make mistakes.

Not to panicuntil you know you have to. Confirm the timing mark alignments. rotate crank manually and confirm valve and piston positions.

  • timing marks on cam and crank lined up according to book should be
  • #1 piston up -comptression stroke #1 cylonder valves closed-no pressure on valve stems
  • #1piston down- power stroke
  • #1 piston up- ehaust stroke - #1 cylinder exhaust valve open
# 1 Pist going down is intake stroke , exhaust valve closing and intake valve opening.
When piston is at tp of compression stroke and timing marks on cam & crank lined up, chk position of rotor,or as piston approaches top dead center, a spark should be generated at #1 plug wire/spark plug.
Cpnfirm all settings so you don't second guess yourself after its reassembled. If, like the man sai,d, any valves got bent. the engine will have no compression and sound like **** cranking and won't gire up. Don't panic until then.Give all your attention to what you are doing witjh the chain. Good Luck and stay in touch.

    ok, no panic yet. Let me review your proceedure and see if I can find the missing link. List each step starting with removing the radiator.



    List everything you took off in order, Go on live chat with me so days don't have to pass between check this and thats

  • Ned C Cook
    Ned C Cook May 15, 2009

    ok, Let's back up and stop second guessing what you have done. Let's look for what you possibly * didn't do. Don't take any offence to any of the below, **** Happens


    • Did you put the crank sensor back on? ( if not, no shame, its been overlooked before.)

    • Did you plug the wires into it? no shame again.

    • Are any wires disconnected you may have forgotten ?

    • Is there oil in the engine?

    • is there water in the radiator?

    have you checked for spark at the plugs or wires this is important vecause you don't know what is talking to the electronis in yhe car.

    One more question. Why did you feel the chain needed replacing?

    Thanks and keep in touch. Still not time to panic.

Need professional tools & knowledge,
just to find a problem

Codes have nothing to do with the need
to install parts & do not tell you what is wrong

Data & Component testing, tells you what is wrong

Maybe you have failed valves on #1

Do a Cylinder Contribution Test, followed by
a Cylinder Leak Down Test & check chain or
belt timing

Cam input data is for fuel control

I have a 85 gmc s-15 v6 2.8 pickup. ive replaced the distibutor,the rotor,coil,timing chain and gears.it cranks but will not start.its getting fuel to the carburator also.whats wrong why wont it start?


It sounds like to me the engine is out of time. Check your firing order to make sure that is right all so check all your wiring going to your distributor. I dont if you bought these parts new or used if used check you coil and ditributor. I hope this might help you. they have a book s-10@s-15 which they sell at any auto store or the library.

No.....you do not have to change the timing chain due to being parked....it is wise though to follow manufactuers specs on WHEN to change it.

There is nothing wrong with your timing chain.
