Recon its the belt dude, as it just happened all of a sudden, the big end has tell tale signs for about 200-300 miles before hand.

Did you stop staright away?? MR2's are supposed to have a non-interferance engine so should kill the engine totally!

Well it didn't sound too healthy .. but as you say, it's "just" happened.
The cams should have markers on them, know anyone with a timing gun?
I know very little about the FE engine though fella ..

I've come across this before - the belt slipped 8 teeth, we reset it and it ran fine - just hope yours is the same bud.....

If it's just the belt slipped, you'll be fine. Get yourself a new one and get it fitted and retimed. As it's already been said, your engine is a non-interferance, so if the belt slips (or, indeed snaps), no damage to the valves is done.
Don't panic dude

The thing is, the 3S-GE and 3S-GTE are non-interface, not the 3S-FE...

How much does something like this cost dude?
EarL
November 16, 2004, 9:22 am
Shouldn't cost that much. It's just a matter of whipping ther cam cover off, and retiming the cams. Not a huge job.

I thought all Mk2 MR2s came with the 3SGE or 3SGTE engine? I've just finnished changing the belt on a 3SGE Celica (1988), the belt had snapped under load and the engine's fine. It's an awkward job but not difficult. I think my Celica Haynes manual has details on the 3SFE, I'll have a look tonight.

The mk2 had an economy version which had the 3S-FE engine in it, nice powerful 121bhp!lol
If you find anything on the FE then that would be great

Contrary to popular belief the 3SGE and 3SGTE engines are NOT (I repeat [u]ARE NOT[/u]) non-interferance/interface. I thought this until I was speaking to my ex-MrT mechanic about it.
If the belt has just slipped you should be able to sort it fine (Like matt said). But if it snaps under load, expect the worst, although you might be lucky.
Don't take chances with cam-belts. Always get them replaced on time

LOL.
Both the 3SGE & 3SGTE engines are not non-interferance.
I thought they were non-interferance until I was put right by my mechanic whilst he was doing the belts on Nicola's Rev2 N/A & Frosty's Rev3 Tubby.

Everyone I've ever spoken to has said that the 3SGE and 4AGE are non-interference.
When I got the cam covers off my 3SGE Celica I set the pistons, in turn, to the top positions and rotated each cam several times (gently) to assure myself that it was non-interference and to check that all the valves moved freely. It now runs perfectly!
I'd agree, get them changed as per spec but there’s no need for major surgery if they break!

Im confused, does all this mean it may be ok then?

November 16, 2004, 2:57 pm
I asked this question a while back. I googled it and came up with lots of contradictory information.
If Limey did what he said, then it sounds like it is a non interference engine. I think that the inlet and exhaust valves clear each other, if they ever end up open together.

Right, so this in turn means that my car may NOT actually be screwed?

Did you not change the belt at the last service?
Anyway I hope it's easily sorted and no harm has come to the engine.

I only bought the car about 5-6 months ago at which point the owner assured me the belt had been changed (I trusted him as he was a friend).
I'm gona have a look at it ASAP.
I can't get insured on Lord Ed's car as its not in my name, so the insurance are being dicks about it, so i have found this nice little ford fiesta ghia 1.1 on the trader! (such a big step down

)
I took a few steps forward with buying my mr2, now its time for the "one" step back, come february/march time i will be leaping forward again with a tuned tubby.
I will be selling all the parts from my MR2 apart from the TOM's scoops and HU, will it be ok to advertise them on here?
As everyone can see, it is for a genuine reason, and I am not like a regular trader or anything, just need some money from my car now to help buy my lil fiesta! (oh and pay Bibbs back of course! lol )

Im 99% sure the MR2 has a non-interference engine, I have seen on several motors when doing the timing belt turned the crank completely over without damaging the valves. People talk about the valves being bent because on high milage sometimes there is a lot of carbon build up on the valves and the pistons. In extreme cases this can cause the valves to contact the pistons when the timing belt breaks at speed.

Had a look in the Celica manual and it does cover cam belt changes on 3SFE engines. If you feel up to changing it and want me to photocopy and send the pages to you email me on limeymk1@hotmail.com.
Have you checked to see if the belt is broken or slipped? It's not difficult, just remove the top cambelt cover, it's held on by about 6 10mm bolts. To check for slippage/mis-alignment of the belt, rotate the crank shaft pulley using a ratchet (19mm socket) to TDC (top dead centre), there should be a mark on the pulley that once aligned with the 0 of a graduated scale on the lower cam cover indicates that the pistons are at TDC. At TDC the cambelt pulley should be in a certain position, there is a small dimple on the pulley just outside of the fixing bolt this should be at the 12 o'clock position when the engine's at TDC.
I'm writing this from memory, I read it last night but couldn't get online to reply so I can't guarantee the accuracy on the campulley markings.

Its kind of a blessing in disguise really, I needed a car thats better on fuel consumption as I drive for my business etc, and something that can carry my drums about...
Im stripping the car completely, selling the bits off it, and then my mate is taking it off my hands. When I can afford it, ill either be going the GT4 route, or an MR2 tubby, probably about february time, but its probably the best option for now!
Im still gona pester all of ya though
