So on my 90 ls400 250k miles my front main seal has a bad leak, im planning on doing a timing belt job. Honestly i’m not even sure if the belt has been replaced before so i would like to replace everything i can (water pump, cam seals, oil seals etc.)
Was just wondering if someone has recently done the same job that could give advice on what parts to replace and where you purchased them? I know previous threads about this have linked the part kits on ebay but those links are outdated and don’t work
im just trying to make a shopping list of all the parts and materials that are required, i wouldn’t want to miss out on replacing any parts because i don’t think i will be doing this again lol

rockauto is fine but make sure you get a kit with an aisin water pump.

The Aisin TKT-030 https://www.ebay.com/itm/29513530335...Bk9SR7Df8bDxYA is a good kit cuz it comes with the hydraulic tensioner.
But then ya need the 2 cam and 1 crank seals. And while you're in there the thermostat, rotors, distributor caps, oil, coolant. And then if you want to, the plugs and plug wires. I think I got all my stuff for about $350 but I already had a new set of wires, rotors, and caps from my last LS400. (parts car)
There used to be a kit I remember seeing years ago that came with everything including the serpentine belt, but I can't seem to find that one now.
