 Posted: Wed Mar 10, 2010 5:23 pm Post subject: Shoddy JCS Rebuild |
 |
|
Long story short I have the engine out of the bus due to head/valve issues. Anyway, the shoddy work got me to questioning the rest of the internals.
Checked end play. 0.012.  Started to clean things up nice and notice this. I assume this is bad. I mean bad. Please cheer me up if I'm wrong but I think this thing just got a whole lot more complicated.
Yes, that is me rotating the #1 bearing by hand. I may be a noob when it comes to engine internals but I'm pretty sure it isn't supposed to do that.

Looks like the case is stamped 080 if so it has been bored out about as far as you want to go on a case..
the bearing movement is not good at all.

Crap, that's what I figured. There's about 12k on this rebuilt longblock purchased from aircooled.net a couple years back. Heads and case have J C S stamped on them so I assume it might have come from these guys roundabout?
http://www.jcsvwparts.com/
Anyway the heads were junk. Valve seats pushed in over burrs. I never could get the adjustments to settle down which is why I pulled the engine to begin with. Appears the seats kept slowly sinking causing my valve lash to tighten. The guides and seats were also machined non-concentrically. I'll try to get some pics up of the shoddy work.
Amazing thing is that the engine was actually running really well. I usually averaged 23mpg in the Westy and it drove fine. Like I said I pulled the engine to diagnose the heads and a continual dribble of oil from the main seal (which totally makes sense now).
So now what. Shortblock? I have new heads already. I suppose I could build up from scratch. This totally shoots an early camping season.

Here are some shots.
The offending SOB.
Head with seats still in.
What exactly are my valve seats seated against? Shouldn't be able to see this much of a gap should you? Even with my limited experience it just looks bad.
Seat Removed
Oh, well I guess it makes sense that the valve adjustments never quit tightening since there were some nice burrs underneath the seats that I presume kept compressing.
Valve Guide
A bit hard to tell from the photo but the ID and OD are not concentric.
Lash Adjusters.
Seriously, check these things out. There's no way this occurred in 12k miles.
The New GEX?
Looks like they even had trouble stamping their own name.
So yes. Everyone has said it before. You get what you pay for. This engine bought us a couple years but now I want to do it right. Do I dare re-use any of the parts from this one, can measuring them truly prove whether they are of any value? I have developed so much skepticism about this thing that I don't know how much if any hope I should have of salvaging anything from it.

| these professional engine builders know 20 times as much stuff as i'll ever know but they operate under a different financing structure than i do so i hope i'll do a much better job with my rebuild. aircooled sold you that? |

I was disappointed. Went through them cause I'd heard good feedback but the longblock was just drop shipped.

stuff like this really pisses me off. it's the 'fuck you, pay me' mentality that leaves the consumer holding the bag. i was in the same situation with a T3 years ago (engine was drop shipped.....from GEX) after the 3rd one exploded, the company who sold me the POS built a real nice engine for me. anyway, perhaps ACN may help you out. have you spoken with them?

As I mentioned in an email to your customer service... this is where I'm confused as well. I'm not trying to start an argument but I did order this engine through your website. If I'm not mistaken the name AVP somehow came up in the mix at the time. I know that for sure the engine was drop shipped and did not come directly from you but the transaction originated with you. I don't know how things all played out, could you have used AVP who in turn used JCS? Maybe this one was an anomaly?
Please, please, understand this is not meant to start a flame war. I am simply trying to get to the bottom of all this and figure out what I need to do going forward.

| Sorry to say but your engine is pretty much a lost cause. Definitely toss the case and heads and adjusting screws. Crank, rods and flywheel might still be good enough to use or reman. Pistons and cylinders are rarely good but possible. I would also be hard pressed to believe that engine could be associated with Aircooled.net |

Why don't you just start fresh w/ a really good core? Build a larger one even.... a 1776cc.
I am surprised it lasted 2 years. |

So you took the guides out of the heads why?
May I ask the PN on those heads?
I give whoever did them an "A" for effort, but it's the results that matter, that's where they blew it. Looks like they tried though.
Sorry about that. |

Maybe the "rebuilder" who John contracted to do the work started shipping engines rebuilt by other outfits?
Several parts that John sells are drop-shipped straight from the manufacturer. Once John provides that other company the details of the order, the other company has to fulfill the order as specified (which may or may not happen). It doesn't absolve John's responsibility of his *sub-contractor* shipping out a POS (though I must say, I'm impressed that engine lasted 12K miles in a bus), or even a *rebuilt* engine the rebuilder didn't actually rebuild, but that's a risk the vendor faces when the product is shipped on their behalf from another company.
