    98 Yukon, The engine restore starts.

    Everything you listed is something I’ve replaced within a year. However, if I was to get a brand new engine, I would throw in the extra $ to make sure there are no faults as best as I can.

    98 Yukon, The engine restore starts.

    Engine knock. Ran out of oil pressure on the highway, there was really no way to pull off instantly safely. So..Knocks like it owes me money.

    98 Yukon, The engine restore starts.

    Hey guys! Dad says he wants me to fix the truck, so. Here I am. I need a good place to buy an engine in the future. I thought about just getting a junkyard engine, but I would rather not if possible. If any of you have done swaps, where have you gotten your engines from? Thanks!

    1998 Yukon, lost oil pressure!

    Haha. Finally had some time to look at it, it was caked in oil and one of the nuts was loose on the solenoid. Fixed.

    1998 Yukon, lost oil pressure!

    Late, but I couldn’t get the starter to engage at all. Now I’m wondering if it has any power at all.

    1998 Yukon, lost oil pressure!

    Little update on the Yukon. Went to go start it, no crank. Checked fuses, battery voltage, all good. The starter relay clicks so I believe the ignition switch is working. Bad starter..? Randomly? Or at least a bad ground.

    1998 Yukon, lost oil pressure!

    Little update for you and the fine gentleman that recommended the Lucas. So far, I’ve made it 400 miles. We dumped about a quart and a half of the stuff into the 4 quarts of oil. As for the leak, can’t tell. Looks like it’s coming from the rear main seal! I do believe I’m making it home...

    1998 Yukon, lost oil pressure!

    Ha! Man, I’ve worked so ******* this truck. It had a 1500 mile road trip, 900 miles in, saw a check gauges light. Thought “Huh. That’s a new one” looked down, saw oil pressure drop to Zero. Went to tick tick, to KNOCK KNOCK. Totally F’d. Pulled over as fast as I could, and I’m 609 miles away...

    Good or bad compression? 98 Yukon, 5.7 Vortec

    Truck has had a p0300 for a very long time. I have a hefty list of repairs I have done myself, and I have had three mechanics look it over. Not one could give me a definitive answer. I would prefer to just be rid of this issue. I have a leak down test kit myself, but I’m moving to a different...

    Good or bad compression? 98 Yukon, 5.7 Vortec

    Currently talking to them just to see how much and how long it’d take for a new vortec. It’s a old truck. Don’t have time to fix it, it’s been beat up and tormented through the woods for about 15 years! If I can get a new vortec in or a rebuild for a decent price, I’ll do that instead just to...

    Good or bad compression? 98 Yukon, 5.7 Vortec

    No, it doesn’t burn oil haha. Not really anyway. They suggested a leak down test, but, it’s a lot more than I as expecting for a simple test I could do at home.

    Good or bad compression? 98 Yukon, 5.7 Vortec

    Hey guys, yup, it’s me again. I eventually had problems again and took it to a shop. I’ve been so busy I haven’t had time to work on it. They said the highest cylinder was 185 and the lowest was 150. I wasn't told which cylinders, but that number caught my eye. Btw, it’s in for rough idle. What...

    Questions about the 2018 Chevy Tahoe

    Hello! Seeing my username, usually you'd think this is a question about the 98 Yukon. Not the case today! Been looking at a 2018 chevy tahoe with really low miles. First thought was what are the pro's and con's of this particular model? It's the 5.3, and yes, it has AFM. I've heard a lot of bad...

    98 yukon, Oil on cylinder #1 Spark plug..?

    Last I checked, FP was 55 at idle, I believe slight throttle was maybe 54/55. I should hook up the gauge again and see what it give's me now.

    98 yukon, Oil on cylinder #1 Spark plug..?

    Even though the Injectors and DELPHI Pump are brand new, I've always wondered at this point if I should put a FP gauge while driving. It's supposed to be above 55 PSI or close to it, correct?

    98 yukon, Oil on cylinder #1 Spark plug..?

    Pulled the plug today, that's actually exactly what I did. Had oil on it. Didn't have time for a compression test, but I'm sure there's something along the lines of either a valve or something else. Will see if I can do it in the morning.

    98 yukon, Oil on cylinder #1 Spark plug..?

    I have a symptom I've never seen before. Very rough idle with some misfires, as soon as you get over 40 MPH all misfires go away...? I swear, this truck throws everything under the sun at me. May be making a call to previous Mechanic.

    Will go get a kit.

    98 yukon, Oil on cylinder #1 Spark plug..?

    All injectors are brand new. Knowing this old engine, it's probably something OR mentioned. Will be doing some tests tomorrow.
