Are Jaycee pushrod tubes still the best?

[donmurray]

I've seen some Jaycee tubes with little sharp protruding tangs that the O-rings will have to slide over, and probably get nicked causing an O-ring leak. Can't imagine what caused these, but it looked like something sharp was pushed down the tube. If you use the Jaycee spring loaded tubes, check the inside of the tube where the O-rings will slide down. I removed the tangs with some 320 grit paper wrapped aroung a tooth brush handle.

As someone else stated, they may also need to be shortened if it looks like the case side seal will get squished out. The only problem is how much to shorten. Too much, it won't seal, and you ruined a set. Jaycee needs to publish some instructions on installing these, and include some length requirements.

Jaycee does have 3 different lengths of the longer, head side, tube available. These are 5", 5.5", 6", so if you have a long tube in a narrow motor, it may be very hard to install. This may explain why some find the install easy, if they have a wide motor and a shorter tube, but in that case the lower spring pressure may not make the end seals seat well.

I made an installation aid out of a 2" piece of plastic hose, a hose clamp, and 2 small corner braces from Lowes. The plastic hose is split to go around the longer tube and clamped in place by the hose clamp. The two small corner braces go under the clamp and stick down so you can get your thumbs on them. The top/upper part of the hose has to be cut so it does not contact the head fins or deflector plate. The purpose of the hose is to keep the hose clamp & corner braces from scratching the tube.

I've been running the Jaycee tubes for over a year now and have not had 1 drip. If there's a drip of anything in the garage, my wife will let me know about it so I'm somewhat anal about having a leak-free engine which really isn't difficult.

be nice to make a leaver operated compressor for these.
my empi jcee knock off tubed after almost 8000 still didnt leek any when I sold the car, but it did take some work before they were ready to use.I hope they have that figured by now...but saddely I have 2 more sets I bought at the same time for my other 2 engines....I may just put a set of scat big mouths on one motor since I have them too and never had any issue with them either.although they are a soft aluminum.

Fast Fab supposedly had the best inner machining process, which is the important area.
