Wow! Thank you all for the high quality recommendations! I have purchased the Seiken w/gaskets $374. It arrives tomorrow. Thanks so much for the fast and enlightening help!

I own a 1996 LX450 and am in need of a brake booster. Trying to keep my budget under $200, instead of the $775.00 OEM from my local dealer. Is anybody willing to recommend an after market brand? PartsGeek has 5 after market Brake Booster brands. They are: Replacement, Seiken, SKP, A1...

Good luck. It worked in my situation and led to the root cause. Although this is the case I really enjoyed the diagnostic routine shown in the attached YouTube.

Starter fluid sprayed over the air plenum caused jump in RPM. Discovered that my EGR Valve stud and nut were missing (gone) and the gasket had swung down. Clamped it tight and truck runs perfect. Stud/nut ordered an on the way. Thanks for your insights.

I own a 1996 Lexus LX450. I rebuilt the engine in its entirety in early 2020. I’ve put 6,000 miles on it with no problem. Although the engine is in good shape, all other systems have 305K miles on them. Here is my P0171 story: Brake booster has been making a sucking sound and sometimes the...

I have a confession. I mistook my head gasket leak for a leaking heater core. Water was splashing down over the transmission bell housing (couldn't see location of leak) and I mistook these for a being a rear heater hose. After closing off the rear heat core I still had leakage. The head...

3 gallons of coolant over a couple of months does not equate to a hair-line crack in a heater control valve. Are you no longer adding coolant? Wait, in AK, does your engine every heat up? Currently 74°F here in Los Angeles.

CAT suffered a catastrophic melt-down causing enormous loss of power. See first photo. The second photo is what it should look like.

From a coolant circuit stand point, isn't the front heater a closed circuit and the rear heater an open circuit? If the rear heater circuit is open all the time it is a continuous fluid flow to and from the engine. Would cutting this circuit out stop coolant flow through the engine?

Good advice. Thank you. Wow! Wits End is only 30 miles from me. Never heard of this place. Will explore.

This was the clue I missed. Thank you so much.

I removed the oil nozzles but where are the check valves?

Three questions: 1. FSM states "Remove the 6 Check Valves…" Where do this reside and how are the removed? 2. Also, do I need to remove the pump shaft oil bushing prior to having the block serviced? 3. Should I remove all freeze plugs prior to block service or is this a service they provide?

Yes, my FSM only gives instruction for full engine/tranny removal. I hoping to not go this route. Of course if I'm able to find these two bolts, then use the secrets noted in this thread, how will I get them back in? Tape them to the socket and spare hands at the firewall?
