what should the compression be on a 52 to-30? also i live in ohio and i am getting ready to work on my tractor and was wanting to wash it real good at a car wash, and its winter here. should i start the tractor up and run it untill it gets warm, then shut it off and wash it, and then after i am done start it up and run it or just let it drip dry? thanks, chris

thats weird on the compression because mine had 145 in each cyl and burned oil worse than iraq and that was with a new head. i pulled the motor apart and found you could see plane as day between the piston and cyl wall. im replacing everything.

If oil is truly getting by the rings at an alarming rate the compression will be very high. I be a wet test would produce the same readings.

With all due respect, I have a hard time believing your engine burned all kinds of oil and you could see daylight between the piston and the cylinder and measured 145 psi in a compression test! Your compression guage must be stuck on 145 psi!

hi chris welcome to a very rewarding hobby.its best to scrape large deposits off .also keep high pressure away from radiator.there are many degreasers available to soak it with just prior to washing.just be careful to not push dirt into old delicate seals.the dash is also agood area to stay away from with gauges and air intake.i found dawn dish soap a very good degreaser for the money . have fun

Most important thing on the compression is that all four cylinders be within 10% or so of each other. If they are all pretty close and probably near 100 or so you are good to go, but a higher number or slightly lower is ok if they are all similar. You may want to do the test both "dry" and "wet." As for washing, just get a sunny day above 25 F and wash it. Put a plastic bag over the distributor and rubber band it tight.

Compression ratio = 6/1
