Unless things have changed, the VDO head temp gauges are not good, and are not temp compensated. I'd strongly consider using a quality head temp gauge like the Dakota Digital (or at least a temp compensated gauge.)
Milling a hole like that is, IMO, not better then cutting a groove in the boss for the K type sender. And when you decide that you are tired of the VDO CHT lying to you and want to change it out for a better one, you are going to be very unhappy when you go to remove and install a new K type sender.

This way the sensor stays in place when servicing the plugs. Clean and EZ. IF this was a 2.0l FI head, a grove should be the way I would have gone too. It was simple to install by pulling the terminals out of the connector. It should be serviceable with the tins in place with long tiny bent hemostats or pliers
Thanks for the tip on the Dakota. If they made a matching gauge for my console I would give them a try but at this point I’m all analog and Black /White (no digital) VDO is beter than running blind |

Just got a new tube of valve lapping paste...The old one lasted 45 years!
Tonight lapped the cylinders to the heads(no head gaskets). I did not lap last time but did have the heads fly cut each time to true. The new intakes were recut (machine not stone) and new guides. Owner of the shop said. These will be much better than the old valve jobs. They lapped the intake , so I decide to lap the exhaust too. Look good. I ran a thread die on all the case studs and pullout all the plugs to clean with a gun cleaning kit prior to final cleaning . Lots of cleaning , then lots more |

Lots of cleaning , then lots more I don't normally lap if the heads have been fly cut and the barrels are new,but won't hurt. Wow you have had some bad luck with this build and hopefully it will be the last , following this one,cheers. |

The windage tray had the same old seals, so a new set glued in place and ready for installation along with the cam bearings. USING A DOUBLE THRUST and setting the endplay at .002 inch flipping the bearing without out the tab 180 degree got my play set about right. The 2 shells work working against each other and canceling out he endplay important to test the play on both half and Assembly to ensure you have it just right

I did pin the shaft on the T4 oil pump. Drilled and milled a 3/32 hole in the housing and when I hit the hardened shaft I switched to an end mill. That shaft is hard so it just left a small mark. NO problem. A aluminum punch and hammer the shaft press out EZ. To EZ! I would pin every one of these moving forward .
With the mark I was able to grind a slot in the shaft for the pin to fit about an 1/8 inch deep with a cut off wheel. Then tapped the hole for a set screw-in the housing. Then cleaned and red lock tight the shaft back into place so the slot is seen in the hole. Intall the pin to full engagement with the new slot with more red lock tight. Installed the set screws so the pin would not come out (more red lock tight) and staked the set screw in place. I feel confident that this pin and set screw are now part of the housing and will not come out. After thinking about the for a moment I should have just welded the pin in place like a short barreled muzzle brake...good enough for the ATF as permanent! Sorry no pics or vid |

With dreams of Octeenerfest, driving on the Dragon and LARGE dyno numbers! This is a dream right? @rfinegan watching and learning from your experiences, Hope to see you at Okteenerfest for sure!! at some point i need to reassemble my OEM motor that dropped the valve seat a couple years ago, and i am trying to decide if i can do that myself, i didnt crack the case i justhave to put the newly rebuilt original heads back on it and wonder if i need to lap the head if i keep the old cylinders and pistons in place, i assume i should. anyway we should get the 914s from SC and NC together and do a engine build how-to clinic! Good luck going forward 3x is a charm right?? |
