Title: 2 having a new engine
Post by: mrsmr2 on February 16, 2005, 18:38
While having the alignment check on mine this afternoon, I had a look around the Toyota garage and saw another 2 on ramps, with a shiny new engine lying on the floor.

Apparently, there was rattling from the engine and Toyota had decided it needed a new one.  I didn't get the full details of what had happened but I did ask if the pre-cats were OK or whether it was drinking it's oil.  I was told it was neither of those things - something else.

It was a Y reg BTW.

I also saw how weedy the original anti flex plate is - hurry up Corky group buy.

During my chat with the mechanic, I also found out that the Avensis is having  problems with pre-cats, and Celica's have a lot of problems with wheels corroding.  He said it's all the range that has problems but mostly Celicas.

The 'rattling' sounds like piston slap, caused by the bores being ovalled. and seems to be the classic pre-cat engine failure.

Piston slap 'rattle' will normally be loudest when the engine is cold, and is under load (full throttle) in any gear, and is most audible around 1500-2500 rpm.

When the engine gets warm it gets much quieter.

From what I can tell, if you have a rattle at idle only then it can be belt tensioner, rattle all the time is probably heatshield, and rattle when cold under load is probably piston slap.
