Weird oil pressure question
1997 ZJ 5.2.
At startup, no oil pressure, can hear lifters clicking. Turn it off, turn it back on, oil pressure comes up, no lifter noise. Oil pressure is a little under 40 per the gage. Give it a little gas and at somewhere between 1000 and 1500 RPM the oil pressure goes away, no lifter noise. I'm going to repeat that--it HAS oil pressure at IDLE. ABOVE IDLE it has no oil pressure. Oil level is right at the top mark on the dipstick. I tried changing the oil and filter and that didn't help. Haven't put a mechanical gage on it yet--the lifter noise at startup and the consistent behavior suggest that it's a real problem and not just the gage and I don't have a mechanical gage. Problem started right after I replaced the plenum pan and gasket. My inclination is that something or other (a lump of gasket, a leaf, a squirrel, or whatever) managed to get into the oil pan while I had the manifold off and is now partially obstructing the oil intake. My inclination is to drop the pan and see if the strainer is obstructed, however if anybody has some less messy alternatives to try that don't involve working underneath it in the pouring rain or riding a motorcycle down to the parts store in the pouring rain I'd be ecstatic to give it a try. |

Weird oil pressure question
Hmmmm . . . .
What if my "other ride" is a resto-rodded 1952 Cushman step-thru? Does that count? Swapped in a 7 Hp Briggs (balanced, ported, relieved, shaved head), body ( this is the classic "turtle back" scooter) modded with an enlarged trunk made to look like a 50's pickup box ... just a lot smaller. It's geared to run at 55-60 instead of the stock 40-45. Budd "Old Crow" > wrote in message ... > "J.

Weird oil pressure question
I know what you mean.
4 Hondas (from 50 - 450 cc) 1 Suzuki dirt bike 1 Kawasaki dirt bike 1 AMF moped 1 Puch moped (hey, they were cheap transportation) And now the Cushman which is a 60 series RoadKing model. I've also swapped into it a Cushman 50 series PackageKar transmission which has a reverse gear and two forward speeds for use with the side car I'm building for the scooter ... getting too old to push the durn thing backward. Just don't ask how many cars, trucks and Jeeps I've had ... not enough bandwidth. <VBG> Budd "Old Crow" > wrote in message ... > "Budd Cochran" > wrote in message > ... >> Hmmmm . . . . >> >> >> What if my "other ride" is a resto-rodded 1952 Cushman step-thru?

The part about Cushmans and sidecars that remains with me comes from the early 50's. I got a drivers license to drive one on-base to deliver newspapers at the tender age of 13. All was well until I made that first right-hand turn just a tad too fast with an empty sidecar... Back then, it seems everyone on base had either a Cushman or an Izetta. There must have been half a dozen Cushman models just on Ramey AFB alone - everything from the low end single speed step-thru slug to the fancy belt- driven variable drive mosels. Learned a lot about wrenching keeping those things running. -- Will Honea |

Weird oil pressure question
Very Cool Scooter!
I have a 1957 Cushman Step Thru Scooter. In all original condition, but it needs a full restoration... I am actually thinking of building a full chromoly tubing frame for it and then stuff 250 cc. motorcycle engine into it and turn into a drag bike/scooter! Then stuff a 255-50-10 inch "Mini" race tire in the back and a pizza cutter size tire up front!

Weird oil pressure question
Thanks, but I've got my sidecar almost done. Being disabled and the current
administration thinks they should get raises while those that have retired or are disabled don't deserve any (but it's Friday and 2012 is coming), I built it out of scounged materials: Spring = mountain bike rear shock Frame = parts of an old bike trailer, a weight bench, and old 1"square tubing in the scrap pile. Swing Arm = the old draglink off my XJ driled and tapped to take a cut down mini-bike axle. Wheel = Mini-bike wheel (won't be used over 50 mph so no worries) Box = scrap lumber / plywood, old piano hinge and a lockable hasp. Hardest part: getting the axle aligned.
