is the 22r and/or the 22re a non-interference or an interference engine? thanks for the help guys! Phil
interference. i have heard that you can cut valve reliefs out of the pistons to prevent contact on wildly built motors. but thats just "heard" never seen it done.
wel im looking to buy a 87 but it needs a timing chain i dont really have any other info on the truck...what should i be looking for? thank Phil
the timing chain is pretty common to go bad. but it really depends on how bad it is, or how long it was driven bad. the drivers side Tchain guide will go out first introducing slack to the eng. then on decel the chain will smack the timing cover and eventually wear through it. when it does it eats through a coolant passage then water n oil start to mix. so i would look for water in the oil and oil in the water. either way the engine is coming out of the car. if it still runs, it will make a sound similar to a bad valve from the front of the eng at idle, it will go away with throttle but come back as it revs down.
a timing chain is a real pain in the a** to do in the truck/car. its easiest to pull the motor then pull the oil pan and do the timing chain. you can pull the head off the motor and do it in the car. but it will suck. all that work with the motor in the truck equals more work then just pulling the eng. im not saying it cant be done or i havent done it in the car, but its a billion times easier with the motor out, and you dont feel like you half a**ed it.
Just do it in the vehicle. You don't have to pull the pan to do a timing chain. Pull the valve cover and distributor and alt. p/s brackets(and the fuel pump 22r) unbolt the the fuel pump cam,there is 1 bolt through the head into the cover to unbolt. Take off the fan and shroud leave the pump on it unbolt the bigger of water pump bolts, unbolt the heater pipes, take off the oil pump, and unbolt the 4 front pan bolts. The cover will slide right out the front. Line up the dot on the upper gear with the arrow on the rocker assembly the dot on the lower should point direct down as long as it lines up then you timing should be fine, which you can check by pulling the valve cover and oil pump. Even if you have to pull the head do it in vehicle the back head bolts can be a little tough to get to. When you pull the head off it makes it nice to have a friend to push back the heater hoses. Also remember to losen the crankbolt before anything ( put it in gear and have someone hold the brakes 19mm socket, breaker bar, and jack handle make it easy.)
I've R&R'd TC's several times and always with the motor in the truck. Can't imagine pulling the motor for a job as simple as that. And you DO NOT have to pull the head for a TC R&R.
