6G Celicas Forums

True, my last car was a camry with the 5sfe in it and I had 175k or so on the motor which was driven with respect and TLC. The oil pump was worn out because my pressure was around 45 I think at highway speed (65 or so) and after it went up to high 50s...60 on a cold day with synthetic oil.

Hi again, well I released the tension on the t-belt and checked the idler bearing by spinning the pulley. It didn't make any noise at all and spun smoothly. I put the belt back on and tightened the belt as described in the manual. It whined again after the car warmed up. I backed off the tension just a tiny little bit and it raps the belt cover at start up until it warms up.

Since my water pump bugged out and I replaced it, do you think I should just get a new t-belt again? It only has about 5K on it. Boggles my mind.

I spun a couple bearings once and just had the crank turned and polished again. I had to pull the engine though to get to the rod bearings. Replaced them, refinished the crank, and then sold the car in perfect running order a couple years later.

Not too sure in your case but it seems quite possible. Also, it seems like you did spin a bearing...at least. If you decided to tear into it again, just check the oil pump to make sure it didn't get chewed up.

Most likely valve seals. Not too bad to do yourself if you have the book, the right tools, and some mechanical inclination.

Do you know if the idler bearings are something they would replace for a rebuild automatically or is it more by owner choice?

Makes sense why the water pump is lighter then.

Lee's pretty damn close to the NY border so I'm way out from the east coast but my buddy lives in NH so I am there sometimes. You guys ever meet up and just hang out?

That's a nice Celica man, you rally it or something?? Looks all hopped up too. You pushing forced induction though it?

Hey guys, that never crossed my mind. How sure are you guys on the idler bearing? I'm not trying to be a jerk or anything but at this point I just want to be as sure as possible it's not something else.


I'm out in Lee man! I see you're also in MA, is that your ride pictured under your name??

Quick edit - I'll be in New Hampshire until wednesday this week, that's where my car is getting worked on. I like the prices on parts over here too, I bought a new water pump for $38 and it's actually decent. I was surprised to see how much lighter it was inside compared to the much heavier factory one.

Hey Everyone, I am new here but not new to celicas. I recently (a month ago) bought my celica from my friend. He had it overhauled 5K miles ago and it runs great.

My issue is this: the engine builder did not replace the water pump during the engine build, why? who knows. If you ask me that was stupid not to do. Anyway, I drove the car about 1K miles since I bought it and it runs excellent. Then I noticed the weep hole was wet with coolant so water pump needed replacement.

This is when I found out that the mechanic never replaced it because it was still the factory one! I also noticed that the t-belt was angled a bit from the failed water pump but it had no apparent damage and I checked it quite thoroughly (new belt).

Well I proceeded with the water pump replacement and it's all assembled. I checked the timing and it's perfect. Well the issue is this: the engine whines now and it didn't before. It kinda sounds like a weak supercharger. When I rev the engine the whine increases so it's timed with the t-belt I think. I then backed off the tension of the belt just a teeny little bit, the whine stopped but now it raps against the timing belt cover. I then tightened it again to make it stop rapping the t-belt cover. It whines again.

What is going on???? It runs great, I have full power, quick start up, no pinging under load, it runs perfect, just whines like a bastard.
