My box can completely test and calibrate the actuator and trubo. Here is a related video:
- Pulled the gears of the cams. BOTH gears were so easy to pull of, that it did not even get more than about 40 ft-lbs on the puller and they popped right off. Normally it takes 80 - 100+ ft-lbs on the puller to pull a gear off, especially the injector cam gear.
They also both looked like they had some el-cheapo loc-tite blue on them, and it was very obvious that they never cleaned the mating surfaces at all.
Makes me wonder what else in that inframe is incorrect. - I shutter to think about it.
We pressure tested the intake at the manifold. Head is done. With all rockers and shafts removed, all valves closed, intake valves will not seal properly. they are hemorrhaging air badly on 4 cylinders into the piston chambers and block. the engine is loosing compression badly on pistons 2,3,4,5. #3 is the worst. Every time you bump an exhaust valve stem for #3, the gauge and air flow into the cylinder on the opposite side jumps wildly like the valve is not sealed very much at all.
This thing needs a new head.
---- We also found out that whoever did the inframe re-used the old head. <-- what a waste of several thousands of dollars on a half-arssed inframe!!!>
This would explain all the low power, lower than normal exhaust temps, and the turbo tables needing to be raised through the roof just to make boost on this thing. <- all his problems are now coming together ... head is bad, causing low compression in cylinders, CAC was leaking severely, turbo actuator was causing turbo to be violently unstable, and all the other thing we have found so far is starting to paint a clear picture of why he was having the issues he was this whole time.
-- I feel bad for him ... real bad.
This is what happens when morons re-build an engine (this was a international stealersh$it in Minnesota).. and this is getting more and more common out here any more. -- Where did pride go ??? === where did the give-a-s$it go? === Where did the proper training and methods for what someone does in these so-called "certified" shops go? == it is truly shameful!!!
