CaliConquestAlex Posted November 4, 2013 Report Share Posted November 4, 2013 I've seen a couple topics here on how to properly degree our cam, but for some reason I'm still confused. Can anyone explain how I can properly degree the G54B camshaft with the engine in the car and the head on and what tools are needed? Link to comment Share on other sites More sharing options...

jszucs Posted November 4, 2013 Report Share Posted November 4, 2013 an adjustable cam gear might help the cause as well. Link to comment Share on other sites More sharing options...

CaliConquestAlex Posted November 4, 2013 Author Report Share Posted November 4, 2013 I have the MK1 adjustable cam gear so i can adjust it, but I do need to learn how to degree the cam first. Link to comment Share on other sites More sharing options...
Shelby Posted November 4, 2013 Report Share Posted November 4, 2013 you need to disable the (correction) intake valve so it don't open or barely opens , and the engine cam be turned back wards IF the chain system is new and tight with the piston stop in place the intake valve will hit it if the valve opens fully you can use the oem TDC mark as a place to start with the pointer with the degree wheel,, most engine i have found to be dead on or with in 1-2 degrees of TDC on the valve one of those small round trash magnets you find in auto trans will help you get a flat surface for the dial indicatorthe magnets can be cut to shape you need Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted November 5, 2013 Author Report Share Posted November 5, 2013 Prettymuch all of that makes no sense to me. lol Link to comment Share on other sites More sharing options...
StarquestRescue Posted November 5, 2013 Report Share Posted November 5, 2013 http://www.b2600turbo.com/degree_your_cam.htm I went buy the lobe center line method. If I recall the mk1 gear is marked back wards, so check it again other pictures you find on the web. Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted November 5, 2013 Author Report Share Posted November 5, 2013 I opened the valve cover up and checked the lash and advanced the cam timing 5 degrees. now the cam dowel pin is slightly past the 12 o clock position with the crank at tdc. The lash was set too tight. The cam card says .010 so that's what i set it to for both intake and exhaust. I fired up the engine and it's running a bit leaner now. Is that the expected result?

CaliConquestAlex Posted November 5, 2013 Author Report Share Posted November 5, 2013 Most of the YouTube videos i found are for v8's without overhead cams or for dohc 4 bangers. I didn't think it would be very relevant. Link to comment Share on other sites More sharing options...

Shelby Posted November 5, 2013 Report Share Posted November 5, 2013 i made a mistake in my earlier reply it's the intake valve you must disable from opening , as yu can see it will hit the piston stop if it opens,, easiest way to do thing is to loosen the adjusting bolt if mechanical adjusters or remove the lifter from the #1 rocker http://www.26liter.us/gallery/albums/userpics/10009/Oct06%2301a.jpg Link to comment Share on other sites More sharing options...

scott87star Posted November 5, 2013 Report Share Posted November 5, 2013 ALL cams should be degreed so you know where they are, Schneider regrinds included. Link to comment Share on other sites More sharing options...
The Rabbit1 Posted November 5, 2013 Report Share Posted November 5, 2013 got the majority of it down, although: is there a centerline a stock hydraulic cam is proven to run better at?what number is most desired on most engines/cams?Is it on the cam card?or is that a trial an error thing?

CaliConquestAlex Posted November 6, 2013 Author Report Share Posted November 6, 2013 What's the rule on rotating our engine backwards to degree the cam? My timing set has less than 3k miles on it. Is there a risk that you can damage the tensioner or that the chain will try to bunch up? Link to comment Share on other sites More sharing options...

Is there a risk that you can damage the tensioner or that the chain will try to bunch up? no your chain is fine ,, but lets say one with 100k miles on it may be loose enough to jump ,,lolbesides degreeing a cam with a worn out timing chain would be a total waste degreeing a cam is about like the first time you did a complete TPS and MPS adjustmentthe first time is the hardest, after doing it a few times it's no problem at all as for center line if you cam came with a center line number , if the valve open and close time matches , so will the center line number , advancing or retarding the valve open and close time will make the same change to the center line number you want to do the valve specs check several times until you get the same number each time before making any changes also if your adj gear has a TDC mark start there Link to comment Share on other sites More sharing options...
