VicsIS350

Ok I have a 1996 ES300 with 188k on it and has oil leaks from valve covers, oil pan...and gaskets that seem to be replaced thru timing belt service. Now my plans are to buy all the parts and have a mechanic friend do the work...I'd like to know what's all being replaced with the timing belt w/ water pump replacement? Are there other gaskets/bearing I need or should replace while the timing belt/water pump are being replaced? I've talked to 2 separate shops and much was explained but verbally not written(I guess to keep me with them) TIA

Cam seals
Crank front main seal
Oil pump gasket
water pump gasket
Valve cover gaskets

Thanks

Any recommendation on alternative from OEM parts? Any links where to purchase?

Did you mean oil pan?

LeX2K

• Cam seals
• Crank seal
• Idler bearing
• Tensioner bearing
• Tensioner (can be re-used if not leaking)
• Timing belt
• Water pump
• Valve cover gasket set (should come with spark plug seals and PCV valve grommet)
• Valve cover compression washers
• A/C belt
• PS pump belt
• PCV valve
• Intake manifold gasket
• EGR pipe #2 gasket (often can be re-used)

"Half moon" plugs must be removed and re-sealed when doing the valve cover gaskets. I might have forgotten something.

Oil pan might be leaking as well, if so then you'll need RTV, and 3 gaskets for the flex pipe, two for the downpipe and one to the catalytic.

Some choices on Ebay

One
Two (my favorite)

I prefer OEM valve cover gaskets, but Felpro makes good ones too. Sorry for the long URL, but this board sensors some websites for some reason (?)

Thanks friend but I'm a tad confused..are all those part mention need to be replaced? Both Advance and Autozone recommend the following:

1. timing belt
2. cam seal/s
3. front crank seal
4. intake gasket
5. water pump and gasket

I wish to change oil pan gasket so added that. thanks

I just listed all the parts required if you are going to do a complete (and proper IMO) timing belt and valve cover gasket job. If you want to omit certain parts, that's a judgement call.

I even left a few things out like coolant, spark plugs and a thermostat.

Just noticed this reply thanks dude

I talked to a local Lexus dealer and was told that this is needed and/or recommended:


2 crank seals(edited 1 not 2)
2 cam seals
Water pump
Idler pulley
Tensioner pulley
Timing belt


lol Lexus Rep just called and stated just front crank seal not rear. Now I'm not a mechanic which if I was I'd follow your route but I think the above mentioned is route I'm taking due to money constraints and my biggest old leak is fixed by replacing crank seal(if I recall what I was told) so no replacing valve covers gaskets yet and oil pan it's not yet determined if it's leaking.
