Continental Z134 Valve Guides

Roger Missildine · Jul 28, 2014

Well hey to all again.
Got the head and block cleaned up on the MF202 this afternoon. Did the liquid check on the valves by filling the intake and exhaust ports in the head with cleaning solvent. After about 30 minutes, went to check and found a couple of the exhaust valve guides leaking... UGGHH
Anyone know where I can get a valve guide installation tool, or if you"ve replaced you guides, what did you use to maintain the proper height? I have the press, just don"t have that tool.

Thanks,
Roger

If they are really that bad- hard to stop a fluid nearly as thin as alcohol from seeping where ever it wants too... but if you really need to swap guides, take it to a machine shop. It is like butchering an animal. An air hammer shatters the old guides, holes bored out, and a Bridgeport, hydraulic press, some thing capable of tons of pressure, has to shove the new ones in at zero degrees straight down to point X.... if a shop does it in 4 hours for a hundred bucks, you have money well spent.

Are there still shops that will work for 4 hours for $100? Thought about having the guides done on the 35 'cause of the occasional puff of blue smoke, but I'm not sure if it's that or the rings. This year the smoke is welcome as the bugs are BRUTAL!!

Maybe I hit the guy on a good day, but I had the new valves and springs from YT shop here for the 202- last spring? The valves could wobble around in the guides, I didn't know where to begin, I cracked one trying to push it out- this is before I learned they are suppose to crack. So I took it there when I picked up my crank around noon- he said leave the head and bag of valve parts on the counter. Around 4 PM I got a call, he said bring a $100 bill and come and get it before 5. I did. Momma didn't raise no fool....

The tractors may be cheap here but labor costs for machinists is not! I picked up a small box (half a shoe box in size) a couple years ago, pins and bushings for the 202 loader. Just over $500 if I recall correctly. I guess I should have told him they didn't have to be an EXACT match. He did do a nice job though......

Thanks for all the replies guys.
Yes, I know engine machine shops are high, but there are a couple in the area that have been around for many years. One is a tad cheaper and I"ve had work done by both with no complaints.
As far as boring the guides and having replacements installed, well I"d rather have the originals and let someone else worry about that later...I'll just have to call and see which one can do it with the proper heights needed.

Thanks again,
Roger
