howdy fellas!
this would be an easy few bucks for a mechanic w/ the shop manuals/ chilton/ haynes manuals. i purchasesed a shop manual off ebay, but want to get the car going sooner then a week from now.

i just bought a 1988 Colt w/ 1.5 4cyl manual(same engine as the 1987/88 mistu mirage) for 100 dollars, not running.
i began to take the engine apart until i found what was wrong with it, it had a bad timing belt. i pruchased another belt and now an faced with havning to set the timing on the engine, i am told there are some model specific marks on the gears and maybe the engine block itself that need to line up/ be in specific positions, can anybody shed some light on this? anything would be helpfull

Aslo, i was told by the mechanic here in town that often, when a timing belt goes bad it damages the valves? true? if i have to replace the valves i will most likely end up purchasing a complete head from the scrap yard.

thanks folks!

any help appreciated.

 

Optional Information:
1988 Dodge colt 1.5 Mitsu

Already Tried:
all i need to know is what are the timing marks and what positions are then needed to be in.

Yes, this is an interference engine so if the the engine was running and the belt broke, it can bend the valves. You won't really know if it did until you put on a new belt and do a compression test.

Reply to Hammer Time's Post: thank you VERY much! can you just answer me a couple other simple questions?

1. how do you perform a compresion test?
im going to set the timing as shown and try to fire it up, any advice?

2.on those helpful diagrams, on the crankshaft pully, it mentions a locating pin, is that a reference to the mark or an actual pin, than perhaps keeps the gear and the belt pully in sync.

thank you very much. accept pending

You use a tool called a compression tester. It has a hose with a gauge attached to it. You thread the hose into a spark plug hole and crank the engine 4 revolutions and read the gauge. Do this on all 4 cylinders and record the readings. They should all be over 100PSI and all withing 10% or each other.

There is an marker on the block that is shaped like a pin to align with the mark in the gear, I think they have actually switched those 2 descriptions in that picture. The pointer is the other mark.

Reply to Hammer Time's Post: so i accepted your answer, i hope the money actually goes to you!

so i went to the store and purchased the compresion gauge

and on one of my cylinders the needle stays firmly on zero, where the other three go around 120

the directions on the guage say that this indicates a sticking valve, would i be correct in assuming that i can remove the rocker arms and pull the valve out? no? replace the head?

what is needed to gain compresion on this piston?

i would offer you more money for you time, but i am ver broke at the moment, so im hoping your generous and have some time on your hands

thanks alot
