What's in your engine?, Found out what's in mine. Options

[Phoenix914]

A couple weeks ago I was given a folder of service receipts from the original owner of my 914. Inside I found what I really wanted - the receipt from the engine rebuild in 1988. What I think are most notable are the 96mm pistons, reworked heads (for $401 - must have been new everything?) and the 272deg camshaft(?). I was wondering if any of you type 4 gurus can give me some feedback on what all this means.

As for how the engine runs after all these years, it is very cold-natured and runs like crap until it's good and warm. After that it's quite peppy and smooth. I've never driven another 914 so I have no reference to make a comparison.

Thanks for the replies, gents. Where is the MPS located? I'll try to check these things out by the weekend. Something makes the car run rough when it's cold. It idles fine, but under load it's crap.

Look at your battery...
Now look down and slightly to the rear of your battery...
The roundish silver thingy with the braided hose connected to it is the MPS...
There is a seal (or s/b) on the end opposite the hose connection...
If the seal is broken, the Sensor probably needs recalibrated, cause someone has 'Tinkered" with it... not a good thing!

The Cylinder Head Temp Sensor is on the same (passenger) side of the engine, down in a hole between the spark plug holes... with a single wire going to it. The Resistor will be somewhere along the wire and above the sheet metal. IIRC, a 13mm deep socket needs to be modified to extract this bugger. I used a Dremel Tool to cut a slot thru the top of the socket sufficient to feed the wire into and still allow the socket extension to fit in the top of the socket. This will trap the wire and let you remove the CHT once unscrewed. To teplace it, fill the base of the socket, just to the point of allowing the hex of the CHT to fit into the end of the socket, and "FEEL" your way back into the threads of the cylinder head... DO NOT overtighten!!! Pelican Parts still had these in stock last summer.

I cut the corner off an extension (I use a grinder). This is a little easier. Use a deep socket. The wire can come out the square opening of the socket at the cutoff corner of the extension.
