Warning, Long post. Holiday timing belt/wp
So been a minute since I posted and this thread needs a bump
So 3 weeks ago I took it out skiing (we've been getting some good snow in the mountains here in CO early). Made it there and back through a nice storm, and I pulled in my driveway around 7pm and it pisses coolant from behind the timing cover.
Awesome, WP went but it could have done it going over Berthoud Pass in 2-3in/hour snow so I'll take it.
So I spent a week working with it, taking it apart, and wondering if it's worth throwing the money into it. Deside to compression check it. Now it's been freezing for 2+ days and it hasn't run so I'm not hopeful but it pulled 150PSI+ across all cylinders. Well f* me I guess it's getting fixed (I wanted the 3.4L in it TBH).
So finally get the parts, tear into the timing first and the belt is cracked all over the place. The WP going was the least of my problems apparently.
Woof right?
Going back together (timing not lined up yet since it had been turned a few times but I did verify all the marks etc at TDC):
So in the end it got new timing, WP, all other belts, new WP pulley, and I have two more pulleys to put on it later and the valve cover gaskets to do. I need to figure out the shim situation though because I don't want it down for a week plus again waiting for shims since it's ski season and the Cherokee is not highway worthy haha
Things I learned
-- Pull the ac condenser in the the front to fit a 1/2in impact on the crankshaft pulley if you don't have the tool to hold it. I didn't have a choice here so it worked well.
-- Be gentle when putting the nuts on the fan, I broke a stud and need to pick a new one up to replace it.
-- It'll take a solid 2.5 gallons of Toyota premix, more if you need to fill your overflow.
-- Take your time and get all your marks lined up and verified before putting the timing covers on. This includes turning the engine a full 360 to make sure they line back up.
-- Having the Toyota FSM with step-by-step instructions was invaluable
Something interesting, I had 12 degrees of timing in it before the t-belt change. Now it's 8 degrees at idle when warm. I didn't touch the distributor during this process so I plan on adding at lest 2 if not 4 degrees to get back to 12 because it was snappier but right now it's running well at 8 degrees.
Have a good holiday everyone!
