    22re a interference motor??

    hey guys, i just sold my 22r celica to a friend and he drove it 15 miles and parked it, and goes back out to start the car and it wont start, cranks but no start, i go to the store and buy a can of starting fluid, and it doesn't fire up,

    one guy who was out side when it hppened said h heard what sounded like rod knock.

    so im assuming the timming belt went on him when he was starting it up after the drive.

    i have priced a kit, it's a little over 55 bucks,


    so does any one know if any other damage could have been done by loosing the chain on start up?

    btw while cranking i dont hear any claking or rod sounds...

    When the timing chain went out on my 22RE in the truck it was the same symptoms. I tried cranking and cranking. There was no damage done even though the chain was bunched up on the crank sprocket. However it did chip the inside of the timing chain cover a little. Not enough to replaced. Took me about six to eight hours to do but it was my first time and in a truck so standing up and working around the grill was a pain. Should be easier in a car.

    Pretty sure it's non-interferance though.

    That's the only thing I don't like about 22RE's, the timing stuff is wimpy in all the later ones. They use nylon guides and a single row chain after a certain year, when it used to be metal guides and double. You're almost guaranteed to find pieces of the guides in the pan after a while.
    A couple places have aftermarket conversions to the double setup or tougher chain guides for the single chain.

    22R /22RE are interference. Sometimes you get lucky and don't bend valves, but pretty often you do. That's why it's essential to keep on top of the timing chains in them.

    what year 22RE?

    Regardless they are INTERFERNACE ENGINES...... however, you have about a 50% chance of bending valves if the chain slips. The chain slips because with the newer single row chain motors the plastic guides for the chain wear though, and then the chain starts to rub the timing cover.... this results in 2 things.... the chain either slips, or the chain wear through the cover and coolant starts leaking into the oil.

    As miekedmr stated... LC makes a double run upgrade... however its a little costly... your best solution would be to get a new chain and run a set of aftermaket metal guids from doaracing, or engnbldr.com

    Feel free to p/m me with any questions... I know these things pretty well

    you can see a new metal guide in this pic:


    and this is a turbo 22re that I just got running

    northwest offroad makes a complete kit to do the conversion also...

    I had an 82' toyota 4x4, that damn engine never quit...


    isn't that a stock supra bypass valve on that turboed 22re? was it already turboed? I know they made a turbo 22re for like one year....

    I was going to say, I see you have replaced the chain before. Then I saw your pictures.

    The plastic guides were done for noise reasons. And yes, when your 22RE is making the heavy ticking, that is the chain eating into the cover from bouncing all over the place.

    the turbo 22R was made from 1984-1988 in SR5 4x4 pickup's. they were five speed stick or four speed auto. They made 120-130HP and about the same amount of torque through 5-6PSI. I own a 88 22r and i changed the timing chain, guides, front mail seal, water pump, all the seals and gaskets to the valve train at about 110,000 miles. It was just beginning to wear into the guides when i did it, and i distinctively remember hearing the chain slapping and ticking worse every day. Best PM i ever did. Now with 185k on her, its time to adjust the valves, adjust the carb, and throw on some LC engineering headers.

    BTW, why is this in the MKIII section??

    They did make a factory turbo 22ret... my isn't, it is a bottom end out of a 94 2wd, ebay 22rte pistons, and a full rebuild kit from engnbldr. I an engine harness for an 87 pickup, a turbo ecu,turbo injectors from an 86 (which got sent out for a rebuild) a used ct-20 and manifold off ebay, grabed a 22rte AFM off ebay too. I used the head and intake off the 89, however had to swap the thermostat housing for an eariler one that has the sensor port. I then decided to run the newer style 89+ throttle body as well.

    I know the 22-RE is an interferance motor because that's how my 83 celica died. It would not start so i cranked and cranked and cranked. After some investigating i found out that it was in fact the timing chain and the guide was broken and it was plastic, and it did wear into the side of the head.
    Anyway that's when i found this link, mostly used for the engine stuff because it's the same engine int he celicas and the pickups and 4 runners.

    That's the first time i've used the link since then lol
    I"ll pm you to make sure you get this.
