Jason's "built" D24T engine build
Well, here is the begining of my "built" engine for my Volvo. My engine is just about worn the hell out, it has tons of blow by and is having a pretty hard time starting when hot. I can see the writing on the wall for it, I know by this fall it won't be starting in the cold weather...
This engine came out of Alex's '85 and had 173k miles on it. The car seemed to be pretty well maintained, and was all stock when we got it. It appears to have never overheated, and the head had never been off it as far as I can tell. It has never been machined for sure. Pretty virgin starting point which is nice. Upon getting it apart, the rings are totally gone, many were broke, and some were worn down to almost nothing (see pics). The bottom end is like new though! It doesn't even need rod bearings, but its getting new ones anyway... I'll be dropping the block off in a few days at a local machine shop to have it hot tanked and dipped (they have a acid tank for cast iron blocks that makes them come out looking new). Plans for the engine include: basic rebuild with new bearings, rings, rebuilt head with new valves, guides, min fly cut, etc... rebuilt rods, shot peened, and balanced balanced pistons balanced crank (going to take it and have it checked/balanced if need be on a sunnen crank balancing machine at a local shop) port and polish job on the head (by me, nothing major, just clean up/smooth out on the intake ports, very minor work on the exhaust ports) NA cam ARP head studs and rod bolts I'll be painting the whole thing CAT yellow.. I know I know, its a green block, but I haven't found a green that really looks like the original color, and I kinda like the industrial look that the cat yellow has. Don't worry, I'll still be telling everyone its a vw diesel, but at least people when they look at it will probably automaticly think its a diesel, and NOT a gasser. Heres some pics:

This engine will also be getting my hotrod injection pump that I'll be building, but not untill after its running with my current pump and broken in. I've got a couple spares and am planning on building one with a Cummins 12mm head, and a 2.8mm lift cam plate. Also planning on doing a HE351 turbo of a common rail Cummins with the bigger pump. I'm hoping to make 250 to the wheels...

Do the bolt holes in the cummins head line up with the threads on the d24t block? |

No I'm talking about the VE pump found on the 1st gen cummins 12 valve engines. I'll be using the pump head (12mm vs. our stock 10mm) and the came plate which runs the head. Our cam plate is 2.2 or 2.3mm of lift. That head can push enough fuel for over 300hp. I'm not sure what you mean by the cummins head lining up with the d24 block, if your talking the cylinder head, no its huge and totally different since its a direct injected engine. The turbo will bolt up to our manifold though since they are a T-3 flange.

Ok, time for an update with pics. I got the head totally assembled with new valve seals. I got the spring compressor from work to check the lb rating on the springs and compaired it with the green book. Didn't want to take any chances with a weak spring since the engine is going to get up in the rpms often. I just got a selection of valve shims today so I'll start adjusting the valves. Cam is bolted in, and I also did some measuring on the NA cam, and I will compair it to the turbo cam when the other engine comes out. Also flat filed the head and block surface, and installed all the head studs... Its starting to look like something!
For any inquiring minds, the NA cam measures .330" lift at the cam. Once I get the belt on, I'll measure the duration at .050" as well. Jason

Time for another update! Its starting to cool off, shit its already the end of october!!! I was hoping to have the engine in already. I have been working on the engine pretty consistantly each night. I cleaned up the valve cover, blasted the exhaust manifold, and finnished the cylinder head. Valves are all adjusted. I'm just waiting on my head gasket. I'm taking the motor mounts, timing belt covers and a couple other pieces with me to work today to clean up in our tumbler to install tonight. With the valve cover on, it really tops off the look. Pretty bull-dozer spec I think. Its gonna look like a million bucks once its in the car!

Wow, those rings are pretty worn for 173k miles. What do you think caused them to break?
I think the cat yellow will look sharp. You could carry the color theme and paint the new diff. cat yellow also.

Thanks... Hopefull it puts down some power. I got the head apart all the way last night... Quite a bit of room for improvement in the ports. Hopefully the port and polish job will help extract some more power out of it.
