Steve's unending Progress thread, Air compressor setup recommendations Options

[stephenaki]

OK, this will be the thread that I keep updated as I make progress. I showed up at 0800 at Christoph's place and he was ready for me with a not so glamorous chunk of metal that is my cars heart and soul.

With a little assistance, we loaded it into my Toyota Sienna, not quite I envisioned a mini-van for, and I was headed back to the house. Upon getting home I had to first make coffee then clear out some space in my tiny German garage. So that everyone has a frame of reference to the area that I am working in I have enclosed this lovely 4x6 glossy of my garage in Germany.

And, for those of you not familiar with the Toyota Sienna, a shot of the engine in the back of the van. There's a lot of room back there for the motor but, it is awkward to get in and out of when loading a motor.

Now to summarize what was accomplished on the 4th of July, engine brought home, tin, impeller and housing, exhaust, cylinder head and cylinders removed. I had difficulty removing the impeller hub. OK, I didn't get it removed, will need a puller and I don't have one unless anyone can give me any ideas how to get it off without a puller.

Now for the requisite pictures of the motor unmolested.

Now based on the initial tear down two problems presented it self first the primary issue with a lack of compression...HOLY SHIT!!! Here is what I found.

Now the cylnder itself was not pitted, it had a build up of corrosion but otherwise in good condition. So I was thinking, maybe I can just clean hone and replace the piston. Well that thought went out the window when I pulled the cylinder directly opposite to it. As you can see by the photo, problem #2.

More importantly, where did that piece of metal go? An initial look behind the piston shows a knick in the inner portion of the crankcase.

I will see if there is more significant damage when I split the case; so it begins and were off to a rocket start here at the 914 follies! Stay tuned for the next exciting episode of "never buy a car sight unseen" later in the week! (IMG:style_emoticons/default/happy11.gif)

Gonna go shower and start working on the motor some more. Plan is to have it completely torn down befor the end of this weekend. I will load up some pictures to my photo bucket album and post the link a bit later.

OK, so today was a rather dismal day in Germany, cold, wet and friggin hail! Needless to say, I loaded up the Pedrinis, Centerlines and winter tires and made a run for post. I dropped the wife and wee one off at an indoor playground called Sensapolis then did what I needed to do with the tires.

After returning home I put the new rubber on the car and decided to see if I could pinpoint the oil leak. I removed the connecting pipe that goes up into the engine tin and the heating air supply or warm air guides as some call them so I could better see where the oil was coming from.

Re-connect the carb linkage on the driver side so I can get her started and crank her up. Once she was warm and idling at about 1500 rpm I looked under the car. No oil. OK, lets finish what I was doing the other day and start synchronizing the carbs.

What I forgot to mention is that Boxter had run the vacuum lines from the carbs into a PVC valve and also run another tube off the oil filler assembly into a perforated plastic oil container. I had connected the lines to two tubes that were sticking out of the left side of the car as I assumed that this is where they went. Well, I disconnected the tubes and set it back up the way Boxter had it done.

So, she's running, I disconnect the driver's side carb linkage and begin synchronizing the carbs checking under the car every now and again. Finally, after about 20 minutes I start to see some oil form on the cooling fins of the #2 cylinder. I get a spit every now and again but nothing like the other day.

Check the pushrod tubes, dry, check the valve cover gasket, dry, check near the impeller, dry. #3 & 4 are also good to go. #1 cylinder fins show no oil forming on them. So my thoughts are,
1) the seal ring/gasket between the head and cylinder didn't seat right or I blew a that gasket
2) I don't have the head torqued down properly but I would think that this would affect both cylinders if this was the case
3) blowby created when I connected the tubes incorrectly from the carbs?

Either way, it is primarily a spitting leak and nothing major at this point so I will re-check torque in the morning and see what she does. I will also do some research on how the tubes are supposed to be hooked up. From the Delorto manual I am supposed to have the vacuum tube connected between the carbs. This would leave the, I assume overflow tube, from the oil filler assembly to connect somewhere else.

Once I recheck things and make sure they are set up properly I'll start her up again and see what happens. If she still leaks then I will order new seals for both cylinders, clean up the head, replace and reseal the head and cylinders. Will obviously have to recheck valve adjustment but at least I don't have to drop the motor. I need to double check to see if I already have the seals since I had acquired two seal sets; maybe i'll be lucky but that is usually not the case for me.

Unless anyone has any other suggestions this is the plan that I will proceed with. Eventually this car will be back on the road again permanently!
