Define Valve Lashing...

[cr8crshr]

That is not what I asked. I don't want to read a book, and I don't need an advertisement ABOUT that book ---- and I might just have that very one. I want to know how YOU are doing it, and what steps you took to make CERTAIN that the cam lobes were on the backside (heels) when you set them.

If you are using the Hughes method, this IS the so called 90* method:

http://www.hughesengines.com/Upload/productInstructions/ValveAdjust.pdf

and also matches the Mopar chart:

As I said before, I use the EOIC method, because then I don't have to worry about firing order. That method works on any engine from B&S to Pratt & Whitney, as long as it's 4 stroke and has poppet valves.

Easy there "COWBOY"...I don't need to be lectured about what I am and am not using for my situation. I merely stated what processes I have been using and the 180 degree process comes out of the book I used for my builds. It was not meant as an "ADVERTISEMENT". And good for you if you have the book. I have also used the 90 degree methods from both Hughes and MOPAR. The results have been pretty much the same regardless of the 180 or 90 degree method. The EOIC method is foreign to me at this stage of the game. And please define what you mean by "backside of the cam lobes" as I have not encountered that procedure or description any where???? 4 stroke I get and understand but "poppet valves???? Not all of us have the Plethora of knowledge that others here have....:jerk:

Geez guys. All you gotta do is watch the valve close and rotate the engine about 5 more degrees and you're RIGHT on the base circle. I do them one at a time. Just personal preference.

I'm with you. One at a time.

I hear ya there and thanks guys. I didn't mean for this to get into a pissing contest. In my own defense I might have been somewhat vague in my description of the problem I am encountering. Just cannot seem to get them to quiet down. I know from my past build that with roller rockers there will be some slight chatter. But this is noise and I cannot seem to get them dialed in. The baffle suggestion will be addressed and then re-lash and see where I am at. This time though I gotta make sure I bolt down the valve covers. Don't need no more oil smoke...:eusa_doh:

if you are using the 90 degree method(the one i use)did you degree your cam and double check to see tdc was correct?if you started at tdc and it was off,all your further adjustments will be off by that amount.

Nobody tried to turn this into a "pissing contest" and you STILL have not answered as to how you accomplish the adjustment.

Hell for all I know what you hear might NOT be lash.

From (probably) several thousand miles away, no photos or videos, or accurate description, we have no idea of your experience, skills, tools, and procedure.

We are just tryin' to get you steered down the road.

Cam is degreed in and I start the lash while at TDC. Thanks for the thought though. Cannot take anything for granted on this ya know...

No worries mate. I fully understand...:grin:

And please define what you mean by "backside of the cam lobes"

"poppet valves????

The lifter must be away from the pointy end of the cam to properly set valves. And you really can't be near the sides of the lobe either.

Poppet valve is the technical name for the style of valves in your engine, or any valve that has that style of operation. Other valve types are gate valves and ball valves. Names are based on the design.

His question indicates exactly why I'm trying to get him to detail how he did this. I was thinking of engines using sleeve valves, to which of course this procedure does not apply.

No biggie. I didn't see it that way. Just a lot of different ways to do the same thing. Might learn a better way who knows?

 

[Meep-Meep]

I've heard of the sleeve valve engines but never seen the detailed operation. Very cool! There are also some rotary valve engines floating around.

Just an update for ya'll...Yesterday I was able to get it running the best it has since initial start up. I still have some chatter that I will keep addressing individually as I get the "LASH where it needs to be. But for the most part, yesterday was the best ever. It is starting to come alive now. Today I will be working on some timing and fine tuning of the motor and the rockers. Thanks to all the input on this. Some very knowledgeable technically oriented folks we got here on this forum. On the downside...there always is on these projects of ours...my power steering pump started to freeze up and the pressure valve on the steering box needs to be adjusted. It pulls by itself to the right when I turn the steering wheel lock to lock. EBooger over at MOPAR ACTION ran a Tech tip on how to do it so I now have to dig that up and get that straightened out. The project is slowly coming together and it shouldn't be too long before it is on the street. By the way...the exhaust note...TTI 2.5 inch with the Dynomax mufflers, sounds awesome..
