mudrat79 Posted October 5, 2004 Author Share Posted October 5, 2004 Ok here is the answer you've all been waiting for...... Ok, as I said We did the compression check in the car, and got weird numbers....Good then bad in all four Holes......So I hand turned it several revolutions, and got good comp in each hole, but only for 1-2 revolutions...... We Know heads are in Great Shape, We have almost new lifters in it, We have new Head gaskets in it, We Figure that what is going on is .......... Dead Cold, Lifters have had a chance to slack off a bit of oil.....Once the engine is Fired up, the lifters pump up.....Now lifters can only go so far cause they have a Limiter clip internally.......So Something in combination with the lifters are keeping valves from shutting 100%.....now bear in mind that they were closing almost 100% say like 97% cause we got no backfire or anything ever......But with Lifters up to capacity, not 100% So at this point I turn the Motor over by hand to re-compress the lifters a bit and squeeze oil out of them......this is whan I was able to get good Comp out of each Hole.....This Told up it was definately in the Valve train.....ie. Lifter issue or Cam issue..... Motor has To get pulled at this Point...... We Pulled the Motor and Pulled Passenger Side valve cover off to see if we can Visually see something not right going on....? Low and behold , Barely Noticeable to the eye, Exhaust Valves ONLY are camming up like they should, but are only slack for 2 teeth on the Cam sprocket ( they should stay slack for about 1/4 Revolution of the sprocket or 25-45 teeth ) then it is ever so slightly OPENING the valve back up.......????? Intake valves Looked Good So To verify that this is indeed the problem ( cam not ground quite to proper Specs) we Tore motor down enough to install a Stock Cam in that head..... We stuck T-belt back on, and With motor and a spare tranny on the ground we Turned it over..... WE NOW HAVE 135lbs in # 1 And WE NOW HAVE 145lbs In # 3 ....... AND IT KEEPS IT........ So we Stuffed Stock cams in Both sides , Making sure we didn't put the Wrong cam on the wrong Side HAhahahahaha.... And it has Great Compression all the way around Now.....Motor will get re-installed on Wed....... We would have and Could have figured this Isue out several Weeks ago, But I had other People scheduled in already, So thank you Brad For being Patient With your BABY JOHN DEERE....... I owe ScoobyWagon a Buck, cause He hit it pretty well on the Head first , and Got close On the trouble shoot side of it as well.......
