you ALSO forgot the same motor you'll use is ALSO found in the 2001-2005 GS430 so this should help broaden the search even more.



i wouldn't sell the car OP i would just install a used motor....do your recommended maintenance while its out though and some extras if you want like engine/tranny mounts,headers if your gonna do any def be cheaper to do while they are out.

keep in mind you dont know what the original owner did to this so while you have it out, if it was mine, i would do my timing belt,water pump, idler pulleys,accessory belt,spark plugs,oil change,etc

IMHO it is simply cheap insurance--I don't plan on a hurricane but I carry a Citizens policy nonetheless. I replaced the timing belt on my '03 with 33K miles a week before this thread began, and I would do it again after reading these comments. The thing deteriorates with time--7 years was, in my opionon, pushing the limit. And $1000 +/- every 6 to 7 years is uncalled for? Compared to my (former) other car, a Mercedes, maintenance on the Lexus is cheap, cheap, cheap. And finally, I use a Lexus (perhaps Toyota) dealer for this kind of critical work because they are, I believe, more likely to stand behind any really costly mistakes it makes than is a private shop.

I assume the SC430 on the LA Craigslist is the subject of this thread.

Mad, Great eye! That absolutely is the car that is the topic of this thread. I also completely agree with your thoughts on the more critical and expensive repairs being worked on by a Lexus dealer. I do believe they would be much more inclined than an independent shop to stand behind any significant costly error resulting from the repair as unlikely as that would be.

Look for a used SC motor and just do a motor swap. It shouldn't cost more than 5k.

$625, does this typically include the full 90k service, plug, lube, drive shaft tightening, etc?

Quick update on the car. I did list it on CL for and just reduced for $13K. The process of finding a local shop that can install the engine has been frustrating to say the least. If I can find a buyer that will take the car as-is I'll just sell it now and buy a new one. Otherwise, I'll go with my best instinct on a mechanic and keep the car. If anyone is interested in the car, they can email me at arctic986@yahoo.com.

Hi folks,

I have an '02 with ~33k miles on it.

I stopped by my mechanic today to discuss this problem and to get their thoughts. This is an independent Toyota mechanic that I have been using for the past 17 years and that I am very satisfied with.

When I first read this thread I was wondering about the 'seized' in the title. While I do very little work on my cars anymore, I have been wrenching on cars since the fifties when I was a teenager. To me, a 'seized' engine usually means one that is 'locked up' from a seized bearing due to a loss of oil. However, that does not mean that the OP does not have an engine that is seized.

My mechanic did some checking ( they have never had to work on a 430 engine with a cam belt busted ) and found that the damage should be restricted to the heads as, apparently, the pistons can take the impact. But I would not recommend betting the farm on that info. They also said that the cost to do a repair would be ~$2000 ( assuming that a piston has not come apart & done other damage ).

They also quoted me $575 to do a cam belt, a water pump & a serpentine belt. I plan on getting this done within a couple of weeks; better to be safe than sorry.

Back in the fifties I did have a Chevy V-8 that had a valve stem break @ ~7,000 RPM; it took out the piston which then took out the cylinder wall. It did a lot of damage but I was able to repair the engine and drive it for quite some time after that. However, one of those in a lifetime is sufficient, thank you.

Consider this just some info that someone might find interesting,
