Need Help Revitalizing My Camry's Engine!

[chuloloco]

I have a 92 Camry DX V6 with 136,000 miles. The engine runs pretty good, but not like it did when I first got it about 3 or 4 years ago. What kinds of things can I do to restore the kick it used to have. I'm not really asking what kind of mods I can do, but rather what kinds of maintenance or additives I can give my car to clean it up and restore its power. Pretty much I just want suggestions to revitalize my engine.

I seafoamed my car about a month ago through the brake booster and have seen minimal changes. How would you put it through your crankcase (oil)?

Thanks for all your suggestions!

Are you due for new plugs, cap, wires, and rotor?

^ I don't know I could be? I really have no idea but I guess it wouldn't hurt to do these anyway. Around how much would it cost? Also, what about a tune up? What do mechanics usually do for tune ups?

Thanks

136,000 miles is not alot on a well maintained camry. I'd start with the basics: do a compression check before throwing any more money at the engine. Assuming you find good compression on all cylinders, just maintain it like you normally would. Unless you like wasting lots of money: If it has adequate power and fuel economy, good compression and no engine noise, a simple tune up ought to be all you need to maximize this engine's potential.
New distributor cap and rotor, if used, new plug wires and plugs. Set timing to specs. Whatever else toyota says to do, and just drive on the engine til it falls apart and it is time to put in a used japan engine or get another car.
