I believe the acceptable spec is 10 psi for every 1,000 rpms.

I can see one problem right now with your in-cylinder waveform. Your vacuum pocket on the expansion stroke and the intake stroke should be roughly the same. Yours is not. Your intake stroke vacuum is deeper than your expansion stroke. Was the in-cylinder waveform taken at cranking or idle...

I have the Lexivon 1/4"and it has worked fine so far but I have not used it that much.

The GMT400 trucks are pretty popular around here and some are going for pretty good prices but for the truck you described, I doubt it would bring $6,000. I have two 98 4x4's and I have had so many people want to buy the 1-ton single cab, long bed truck. My 1/2-ton extended cab Z71 truck is a...

I'm saying that you have to put your multimeter in series with one of your battery cables to measure what your amp draw is. For example, you unhook your negative battery cable. You attach the red cable of your multimeter to the end of the cable that you just disconnected. You then hook the...

You have a parasitic draw. Have you used an ammeter inline to one of your battery cables to see how much draw you have and have you checked voltage across each fuse in the engine compartment and any fuses that may be inside the car? There is a specific procedure to use to find parasitic...

I just always hook it to a garden hose from an outside faucet so I'm not sure about the water pressure. I have used it successfully for years without damage to any radiator or condenser. It depends on your specific vehicle whether or not it fits in between the two. Sometimes you have to...

I would use emission hose or something rated to handle oil so that it doesn't soften the hose and cause it to collapse under vacuum.

I used a click style torque wrench recently to torque the transmission pan bolts up on a 97 GMC truck. Worked great. I also have several beam type and a 3/8 and 1/2" Quinn digital torque wrenches from Harbor Freight. I also have the Harbor Freight Quinn 3/8 and 1/2" digital torque adapters...

Yesterday I replaced the Duralast Gold alternator on my 92 Cavalier. It had started making some noise last year but Autozone wouldn't replace it just for the noise. Last week coming home from a party, the battery light started coming on at about 65 mph but would go off below that. Charging...

I use the Radiator Genie water sprayer for my radiator and condenser. It works very well. I also use the air nozzle on them sometimes...

Well, only two things could really cause the increase in the oil level and that is coolant or fuel. Does your coolant level stay the same? Is this engine direct injected or a combination of both?

Recharged the AC in my 92 Cavalier. Last year when I went to use it, it had quit working from the year before and I didn't mess with it. This car is still R12 because I have a lot of it. I replaced the compressor, dryer, and the compressor manifold hoses in 2019. In 2021 the system was low...

I made all new rear lines that went from one rear wheel to the other rear wheel years ago for a 96 F-150. I bought the line and used a brake flaring tube and some connections and got it done. It wasn't the prettiest job, but it worked and never leaked.

Have you looked at fuel trims at higher rpms? Take it up to 3,500 rpms or so and look at your fuel trims. Typically, if they get better and close to normal, you have a vacuum leak. If not, it may be a MAF or low fuel pressure issue.
