![]() It rests and close to 0 at lights and almost never rises above 1/4 on the gauge. My LX450 is now at the point that the oil pressure is so consistently low it scares me. I've cheated for years and thousands of miles running higher weight and feeding them oil regularly. I have three 80s, all 1FZ-FE engines and they all need the valve seals done. If I get this truck back together properly, it should be rock solid for another 220k miles and that is the real win. It's a bunch of work, but between the forum and YouTube it's doable with good tools and an occasional helper and it will save you a ton of cash in labor. Then, since it's kind of a PITA project you don't want to repeat, you should knock out as many things in the engine as you can while you have access - PHH, coolant line next to PHH, all new vacuum lines, all new gaskets and seals, deal with the steering pump while everything is out of the way - that kind of sells a kit of all the gaskets and seals to do the head gasket and all related items. to get the head off is serious labor hours. That figure climbed to $650-700 for him to set the cams and check to make sure the valve clearances were all in spec as well. The local NAPA machine shop that has done work for a few other MUD members and was recommended by my inspection mechanic quoted me $300 for valve seals, cleaning, decking and pressure testing the head. This is what I am seeing locally in PA and this is just for the head work. After a lot of scouring, I haven't been able to find a price range on this anywhere, probably because it seems a bit specialized.Īny feedback on this would be appreciated - how much should I expect to pay to fix this if I were to pick up this truck? Are there any other obvious issues that are probably contributing to the engine issue? Any other thoughts?Īs I am in the middle of the head repair I have a fairly accurate idea of costs. I've seen that this work can be done when the head is off, or if the mechanic is skilled, using rope/air pressure with the head on. I don't hate the idea of doing a repair, and getting some PM at the same time, but here I'm mainly wondering about the cost of the individual problem itself.įrom what I've read and been told by mechanics, this is probably leaky valve stem seal. I'm trying to get fully informed about the implications. I had a pre purchase inspection done, and it turned up a puff of blue smoke when starting up after sitting a few hours, in addition to known oil burning/seeping. I'm looking very seriously at picking up an FJ80.
