update:
I just finished up the timing belt job, replacing the : timing belt, water pump, timing pulley, and timing tensioner. I probably should have replaced the crank and camshafts seals while I was in there but they looked good.
I did end up purchasing a few new tools : 250 ft lbs torque wrench, lisle spill free funnel kit, stud remover socket set, E3(star) impact socket set, and wheel puller set. Beyond having everything I needed to do the job the hardest part was holding the engine to torque down the harmonic balancer.
I did, have one of those oh crap moments though. I had just got everything back together and was attempting to start the motor. It took several cranks and spitting and sputtering around but when it fired up, it smoothed right out. I thought for sure that I had screwed something up or got a tooth off. I have put a few hundred miles on it so far and it seems good. No leaks and to me it sounds even quieter than before (almost like it isn’t running).
Good video of this exact motor in a Lexus: https://www.youtube.com/watch?v=DI60MOkf168 .
I have also replaced the front valve pan gasket with out any issue and will do the back one later this summer.
Thanks to everyone who read/replied to this thread! Gave me a lot of good info that helped me complete this job with out any real issues.
Thanks so much! My rear gasket really has the smallest of leaks(just a little out of one corner vers all across the front of the front one)…front one is way worse. I’m thinking I will just replace the front one before my trip and when I have the van parked, for the late spring/summer, I will put the back one on. I will have it all apart doing the timing belt replacement then as well. Back one sounds like it will be all kinds of fun 🙂
Going on a long trip in the next few weeks and I know I won’t have time to do the timing belt. I might be able to take care of the valve cover before leaving. Looking at around 2400 miles round trip. The cover isn’t leaking a lot but it would just be one less thing on the road. Plugs are pretty new.
I will drive it until I haul it to a junk yard… if I can put 400k on it and not have to replace the engine/trans I’d be happy…love this little van… wish I had a truck instead but I can do almost everything I need with it.
I am not having any problems with over heating. I’m pretty sure I don’t have a blown head gasket… I was just doing work on the van to prevent major breakdowns later. It still has the original timing belt and I know it is way over-do to replace… the van is my winter vehicle and when I park it this spring I will do the timing belt change.
ok…assuming you were just talking about the timing belt replacement….looking at:

Thanks for the reply. I will replace all of that this summer.
Any thoughts on the valve cover gasket replacement that I will be doing in the next two weeks?
It is a cable connected and I traced it down… it is connected and moving the plastic flipper ( also can tell that the air pressure lessens when on hot vers when on cold) .
But now I have a new issue that just started happening when I tried to confirm that I still had good back flow through the heater core. I am now getting lots of humidity on the window…so it’s looking like I put too much pressure on the the heater core with the water hose. Well long story short, I will have to replace the heater core now…wahoo(2-3 days of my life that I will never get back).
I ended up putting a bypass in to take the heater core out of the coolant flow so I can drive it. Just FYI if anyone thinks they can just use electric heaters in cars to replace the fluid one…get ready for a cold ride. Thanks for your response and time.
