02 Toyota Sequoia oil Pressure?

all of the above junk is great info if it really mattered or you had 150 k miles on it, you can try a factory oil filter from toyota they have a valve in them to help oil drainback while setting

I would be little apprehensive, as well. Here is a simple test you can do yourself. Remove your oil filler cap and look at the back of it. Is it coated with brown, or goo, or flaky crystals that you can scratch with your fingernail??When you look inside the engine, are the engine parts you can see clean, or coated??This is sludge and/or varnish. Whatever you see here is the what your entire engine looks like inside. Adding Slick 50 will only cover things up and may even worsen things. Sometimes it can make your oil seals leak. Your engine has a hydraulic (oil pressure sensitive) timing chain tensioner. It's job is to keep your timing chain at the proper tension. If there is a lot of "muck" inside the engine, then the passageways that keep the pressure up to snuff are being compromised. Also, you have an oil pressure relief valve built into your oil pump that is supposed to regulate the pressure. At start-up, more pressure is required until the oil warms-up to it's its best viscosity, then the relief valve changes the pressure to match. The real problem here is probably varnish and sludge build-up in these high precision assemblies. The right answer is to do a de-sludging!! Most owner's manuals are adamant about not using oil additives to their engines; usually, nothing is required. The best oil I've seen is the Mobil One 0W-40 oil that surpasses all auto maker's requirements, and protects best at start-up. But if you have sludge build-up, then nothing will get through your oil passageways at start-up, until these areas are as-new clean. I would be happy to E-mail to you the procedure I have found to work the best. Just ask me!
