I rebuilt the engine(T-chain, bearings, pistons, rebuilt head) Fired it up but I'm not showing any oil pressure on the gauge. How do I identify the problem? (Pressure switch? Wiring? or?) rj Re: No oil pressure (87 4runner) [Re: hazman] #570221 02/18/05 06:08 AM Joined: Oct 2002 Posts: 15,887 Fairbanks, Alaska kewlynx Toyota & Classifieds Moderator Check to see if the wire is properly connected. If you want to cross check the oil pressure, put a gauge on one of the oil galley ports to check it. After that, wiring/gauge. With it having a broken timing chain, I'd recommend a leakdown check as well. This is an interference engine, so you might've clanged the valves. Easy enough to do as a precaution. http://www.walkablecommunities.org/ Democracy is two wolves and a lamb voting on what to have for dinner.

There are 3 hidden plugs, 1 will let you know immediately. Front and back of engine block along the main line with the filter. The most forgotten gallery plug that results in ZERO pressure on the guage is the small plug directly below the sensor and filter in the oil pan. Try remembering if you put that puppy back in, without it the oil is picked up by the pump and redeposited in the pan prior to filtration. ~Darin <img src="/forums/images/graemlins/baby.gif" alt="" /> 88' 4x4 *22R-EB Gen II* 87' $Runner *22R-EB Gen I* 85' Sillyca 22R-Esq "I LIVE IN MY OWN WORLD...THEY KNOW ME WELL THERE" Moderated by  4Crawler, 4x4Wire, kewlynx  Hop To Mitsubishi Forums ------  Mitsubishi 4x4 and SUV Tech  Mitsubishi Diesels  Mitsubishi ArchiveToyota Forums ------  Early Toyota Trucks  Toyota 4Runner, FJ Cruiser &...  T100 & Tundra Forum  Tacoma Forum  Toyota Tech ArchiveJeep Forums ------  Jeep Talk  Jeep TechIsuzu Forums ------  Isuzu 4x4 & SUV Talk  Isuzu 4x4 & SUV Tech  Isuzu DieselsKia Forums ------  Kia Talk  Kia Sportage & Sorento TechOff Topic Chat ------  4x4 Gallery  Off-Topic Chat  Recreational Access & Land ...  Politics4xForums ------  Outdoor Gear  General 4x4 Discussion  Tools and Fabrication  General Communications  Amateur Radio  GPS and MapsParts Bin ------  Private Party - Garage Sale  Private Party - Items wanted  Vendors, Hot Deals, Group Buys4x4Wire Back Yard ------  Suzuki Forum  AZ Crawler Crew  Cal-Nev Crew  General Ford 4x4 & SUV Forum  General Dodge 4x4 & SUV Forum  General Chevy 4x4 & SUV ForumFeedback & Testing ------  Problems, Questions, Suggestions4x4Wire Staff ------  Forum Moderators  Problem Threads Print Thread Switch to Threaded Mode 5 Excellent 4 Good 3 Average 2 Bad 1 Terrible View Profile Private Message Follow User Forum Posts View Profile Private Message Follow User Forum Posts View Profile Private Message Follow User Forum Posts
