1998 Chevy Blazer 6 cyl Four Wheel Drive Automatic 107000 miles
Hello all. I am new to this site. Looks like a really good site. I am just getting into engines and working on them and all that stuff. I am only 20 and want to become more knowledgeable. Anyways here is whats going on. For the past year or so I have had a sticky lifter. And about a month or so ago I decided to dump CD2 into my oil to see if I could free it. I drove it for about 15 miles and when I pulled into my destination I realized my check gauges light came on. My oil pressure read zero. I proceeded to drive home. About a 20 minute drive. When I accelerated my vehicle was reading 20 psi and when I braked it went down to nothing. Was this coincidental that it happened right after I dumped this CD2 in? I let it sit for about a month without driving it. I drove to the garage which is 5 minutes away. They flushed it and put lucas in the oil. Pressure came up to about 40psi dropped to 20 when I braked. This held steady for about a week. Now after my engine is as hot as it gets it goes down to about 20 psi when I accelerate and down to zero when I brake. I drove it for about a half hour to see if I could duplicate the problem again this morning and it did happen again. I have not heard any unusual noises coming from my motor. No clunking or nothing. Also when my car is shut off and I go out and look at it later it says I have 20 psi when its off? Could this be a bad gauge or sending unit? Clogged pick up screen etc. Hopefully my cam bearings arent shot. Thank you in advance, Andrew
