Thanks again for the input! I’ve never done a pressure/vacuum check but I’m going to go look at the thread now. If it failed the test, how much would you deduct fo cover time/parts in fixing it? Also read if it was revved in neutral too much it could damage tranny bearings and ruin the AB which isn’t available anymore. What is an AB? Any work arounds? Hate to drop $3k+ and end up with something non-repairable. Please educate me! Thanks again for the responses!
If you fail a pressure test, then you have to go over your
Engine with some soapy water or something similar to find what is leaking. Could be a head gasket, base gasket, crank seals, intake/exhaust manifold, etc. some of those can be fixed relatively easily, others will take some doing.
Like CO mentioned, the rubber intake boot on the 35 y/o Odysseys can crack causing a large air leak, lean running Engine and if let go, a blown up Engine.
The AB is a gear inside the transmission, (or 2 gears, A and B that are 1 piece), there is/are needle bearings inside these gears that can run dry if the transmission is revved in neutral (because it is a splash-lube system, if the bottom gears are not moving, no oil will get splashed), when the bearing fails, the gear will usually also fail. Most people overfill the transmission which can help, but the best way is to limit how much you rev the Engine in neutral, then you probably won't have any issues.
As long as you do the pressure test, and pass it, and are somewhat careful, you probably won't have any issues.
Definitely want to read up as much as you can so you know what you are getting into.
