I have replaced belt one time last month no problem this time i did head and im not sure how to find tdc since if i put timing cam marks together as book says and i rotate motor to compreson stroke it will give compresson on intake and exh do to valves closed if i put belt on to check how to say the crank is not on exh stroke how do you set up or does it not matter do to it fires on compresson and exh stroke i write this do to puting on blt 4 times and keep getting back fire out intake only i was a gm machanic for 20 years and did 100 head gaskets and over that in the 80s on timing belts but you could put finger over sparkplug hole to find compresson stroke not on pt crusier 2.42002 please tell me what im doing wrong thanks larry

I can not find in any book how to find tdc all books say mark gears before remove what if broke it dosent say how to find tdc so i cant belive it dose not matter also i had no spark for 2 weeks and last nite i found no codes but the coil plug and cam sensor are the same and will fit perfectly and this caused 2 weeks problem i thought ecm was bad i changed aasd relay and still no spark nowere in any book it tell to watch for this mose if not all plugs will not plug in to other plugs or reach this even looked right so i fixed this and now i may be confused on tdc i do belt all the time for income for other people but when it comes to my car i over think the problems i will be happy to pay if your ansewer fixes my problem and dealer or any shop will not work on my car do to me doing 3/4 of the work and nearest shop 30 miles thanks larry
Dear sir i have 2 manuals and i sent head out for resurface so the valves were redone also on 2.4 the mark starts 1/2 tooth off below on exh cam and crank it starts the tooth must be at trailing edge or timing will be off but my question is about tdc how to tell if it is compresson or exh stroke when belt is off do to all valves are closed at this point
Sir your ansewer is not what im looking for on a pt cruser you must line up the cam and the arrow on crank my question is how do i know if im on comp. or exh stroke piston is up all the way but what stroke. i cant put belt on if exh . stroke and i need comp. stroke this is how this car is set up but manual shows how to replace belt when still on car so you can line up cam marks and if crank marks is not on rotate 360 deg. to get comp. stroke do to 2 turns of crank or 760 deg. is 1 turn of cam gears so with broken belt i can not set to crank mark because i do not know what stroke im on is there a way to tell if i put belt on wrong and turn motor over to comp. stroke i will bend valves so how do the dealers do it thank you larry finding the comp. stroke on 2.4 pt cruser
There is no stroke to worry about when setting a timing belt. Just line up the marks and be careful when rotating the crank with the belt off.
