bent a valve a push rod AGAIN!

[toolmaker98]

All of that has been checked and or bypassed. I read on another post that soaking the push rods in oil overnight was something you should do. Would that be like putting oil in the oil filter before you put it on. The front cylinder is oiling like it should.

 

[Theycallmecrash]

nope.

the only thing thats makes sense is the oil passage to the lifters on that side are blocked. but, let me ask this, when it runs, does it sound like the lifters arent pumped up with oil? what im wondering is if the the oil gets blocked after the lifter, they build too much pressure and bend the push rod or over extend and the lift becomes too great resulting in a valve hitting the piston. just to give and example of what im thinking, the rocker arms have little holes drilled in them where the push rods connect to allow oil to spray on the valve train...well if those hole werent there or completely blocked, then oil pressure spikes in the push rod and lifts.

I didn't hear it run. But he said it was more quiet then normal. He believes the lifters are pumping up. And that there was not any abnormal ticking sound from the rocker arms. When he had it running that the oil was pumping randomly, on the off and so on. Again this doesn't sounds possible. I totally agree with all of you. I am getting it back next week, and I am going to play with it for awhile.

Its something simple and basic, these are a really simple design, pretty bullet proof, Its going to take VERY careful diassembly and reassy to find it, then it will be "DOH! Forehead slap!"[mad]
dont ASSUME anything, doa very careful and methodical teardown and check every little detail. I am curious at this point.
When in the Air Force, we never were allowed to close up a aircraft panel without a second person checking your work,a second set of eyes is critical. You would be amazed how many well trained and very experience mechanics would forget something or make a basic mistake. Often times performing a routine task they have done many times over the years.

Yes I agree. I have never had my bike apart. So I do not plan on taking it apart very far. And I told my mechanic that I would talk to him before I took anything apart. And I plan on take notes on what I did and the results. I have another question about lifters and pushrods ( might be a simple question and I think I know the answer, but I will ask anyway) does the lifter only push oil up the pushrod when it is being compressed? When the lobe of the cam is at it tallest? My mechanic has made a plate to cover the oil groove supplying the lifters, and rigged up a hand pump to pull oil from the oil bag, straight into the oil I'll filter fitting (bbypassing the filter and pressure valve in the filter) but one of the lifters is in the down position so the oil in the lifter is covered up. So how would it oil if that hole is covered up. And if the lifter only pushes oil up the pushrods when compressed then his bypass is not going to work

Can you change lifters front to back and see if other cyl gets oil to top end?

 

[toolmaker98]

Yes that has crossed my mind. But I think I might have found something maybe. I dug out the old set of lifter that he took out last year and they are made a little different than the ones me showed me. I don't know what the ones look like that are in the bike right know. I will find out Monday or Tuesday.

OK I have the bike apart where I can see the lifters. I have removed the lifter and pumped oil into the system with a hand pump. I am getting oil to the lifter hole. So I cleaned the old set of lifters (original set) and put it in the hole I am getting a little oil into the lifter, but not enough. So I bought a pump that you drive with a drill. I have modified the plate he made to put oil into the oil groove around the rear cylinders lifter holes. Still nothing up the pushrod.

Is there a drain plug in the bottom of the engine? I want to drain any oil that may be in the bottom,then pump up the system again to see if I get any more oil out the bottom.

 

[toolmaker98]

Well I did get the top end to oil on the rear cylinder. This is how I got it to do it. It only drips out of the rocker arms. And it seems that I have to have a lot of pressure. I have to stand on the bulb to get it to oil

 

[toolmaker98]

Does anyone have a oil pressure gauge on their bike,and if so what kind of pressure does it run at idol?

 

[toolmaker98]

Any suggestions on how i can start my bike without the tank in place. 02 s3t with fuel injection. How about suggestions on a cheap electric fuel pump.

 

[toolmaker98]

I have it rigged up so I can start it without the tank on. I ran it for about 10 minutes, long enough to get the cylinder warm. But still only a drippable out of the rear exhaust rocker arm. I have 20 pounds of oil pressure at the spot where the oil pressure switch goes. So my question is how much pressure should be there. And would a aftermarket pump be worth my time and money?

 

[twobuells]

My 2001 service manual states at 2500 RPM 10 to 17 psi. At idle 7 to 12 psi but these values are for a warm engine that has been run for twenty miles at or above fifty mph. They do not give a cold specification.

 

[toolmaker98]

Well I have oil to the top end.

I have one more question.
I have been told,have read about it, and have I have seen it. I don't understand why more people don't have oiling problems. At idle there is no oil squirting on the valves. I don't now what the minimum rpms are. But I had to run mine 2000-2500 to get oil squirting out.
1) am I wrong about this?
2) should I see oil squirting out at idle?

Roller bearing crankshafts do not require large amounts of oil either volume or pressure.
