You work for toyota? Do you find that seals leak because the seals are bad or because the crankcase breathers are all blocked up? I have found that engines with blocked breathers will blow out new, correctly installed seals not solving the problem, but resulting in more work and cost.Originally Posted by Gavatron
I've also had engines with well over 140kkms on them that I would not touch the seals if they were not leaking.
Would you replace timing belt idlers and tensioners? spark plugs? leads? dissy cap? clutch? get flywheel machined? replace flywheel bolts? get injectors cleaned? replace all hoses?
Where do you draw the line?
Woud you (specifically) do everything that you're suggesting, if you bought a camry?
On the 1UZ I replaced the front and rear main seal, but I didn't touch the cam seals because they are $60 each (genuine only) and you have to pull the VVTi actuator partially apart and take the cams out to the change them (not sign of leaking and clear crankcase breathers). I had a toyota engine manual but I still decided against doing it.
I did not replace the waterpump - this was a calculated risk as pretty much every 1UZ I've known to have been involved in a conversion did not ever need the pump changed, even well after 100kkms. It's also something that usually leaks first so you are not that likely to get stranded by a pump that's starting to fail.
I also did not get the injectors cleaned, nor did I replace sparks plugs (they will be getting cleaned and replaced over the next month, but they didn't get done two years ago).
I did however, replace the timing belt idler and tensioner even though the originals probably would have been fine. Ed probably spent somewhere between $10k and $20k on his engine and made the call that his original ones were fine.
You have to draw the line somewhere otherwise the costs escalate for (sometimes) no benefit, and can actually cause problems if you don't replace them properly.
The body mods are not my thing either, but I'd like to see this conversion happen, whether or not the engine is in tip top shape. Provide the advice, but don't harp on it (please ).
