GS714

Hi Folks.
I am new to this forum and Lexus. Am thinking of installing the Daizen poly bushing on my 2001 Lexus GS300 but having difficulty contacting Todd at TM Engineering. Is TM Engineering still in business? Carson is about 20 minutes drive from where I live but the guy haven't reply to my emails or voice mail. By the way, Do I really need to change the cam seals and the VVTi cam gear when changing the timing belt. I also think the water pump can be done separately. Any folks from Orange County Socal happen to know any good local Lexus mechanic or garage in Garden Grove or nearby, I need some pointer? Thank a lot. (Pardon my grammar)

Hi,
I tried to buy from TM Engineering and my emails were never returned. I ended up buying the hard poly bushings on ebay. (8-1124-BL Prothane Polyurethane 14MM Rear Sway Bar Bushing Kit, which came with the grease).

No, why do you ask?

I just bought the car about two months ago. The timing hasn't been replaced yet . Previous owner told me. The mechanic where I have the car service told me that you may be as well to replace the water pump, cam seals (also told by Lexus of Westminster) and the Sproket O-Ring Seal (maybe even the gear assembly itself while replacing the timing belt. I noticed that the water is not driven by the timing belt, is that correct? Thank a lot folks.

He means a previous post about tm engineering, as many folks have had issues contacting them, and/or receiving their parts. Search for it, it's there..

The water pump is not bolted to the side of the motor like the alternator or ac pump. It is bolted on from the front and extends under the timing belt and cover. So you will be essentially doing the timing belt job over again if you do the water pump later. Same with the cam seals.

If the cam seals aren't leaking, you can leave them be. But they are only a few dollars, so you really should do it when you do the belt. The cam gear is kinda pricey so you could skip that is it's not leaking from where it's mates together...

This doesn't make sense. It makes perfect sense to change the crank and cam seals while doing the TB. Seals/gaskets are a wear and tear item. I can guarantee that it will leak before it gets to 200k. These seals are like $5 a piece so it only makes sense to change during the TB change out due to the labor it will cost just to replace the seals.

I was able to drive to carson and picked up several items. Tie rod ends. Lower ball joints and all bushings offered. I guess its good to be local
