QUOTE(Jake Raby @ Sep 5 2011, 03:30 PM)  The lowermost pic of the oil pump shows a failing pump.. See that idler gear shaft?? Its become loosened in the body and is waiting to contact the camshaft. This is a common problem with stock pumps and the reason why I haven't used one in over 15 years. Once you lose an engine to that occurrence; you learn the lesson really quick. I can see wear on the camshaft gear but the oil idle gear shaft seems to be fixed in place. I don't know how it should look like so I took an other picture to show it from the side. I also measured it and it seems to be about 0.5mm away from the camshaft, unless the camshaft has some play. Anyway, what are my alternatives for the oil pump?   |

There ya have it... What I said earlier.. This happens all the time with stock pumps. If those rivets get worn too much the cam gear becomes detached and you have a mega mess to deal with.

QUOTE(Cap'n Krusty @ Sep 5 2011, 12:55 PM) I don't see any comments about temperature sensor location in any post other than yours. The type of case has NOTHING to do with oil temp sensor fitment, and the stock one will fit fine. Second time I've seen this misguided notion in the last few days ................ The Cap'n You're right, I didn't mention that. Zach was reading my mind. There ARE some cases which won't fit a stock 'long' oil temp sensor probe. Ran into that problem on a bus once.

QUOTE(dlee6204 @ Sep 3 2011, 05:29 AM) dlee6204, WOW! That's the MOST ABUSED Type IV I've seen. From the scrapes on the pistons along with the distorted ring land it is obvious that the engine SEIZED! It's a good plan to replace pistons and bores, heads, oil pump, bearings and gaskets, but first I would want to have the rods checked for straightness. Whaddya' think? Good luck, Terry |

Good luck, Terry What are you talking about?! The pistons and cylinders are pretty fine. I would have used them again but I want to make bigger engine. The scratches on the piston head have no importance and are probably from a previous rebuild since the cylinders are very nice. There were no signs of stress on any parts so far. Pistons pins are fine, lifters are like new. It seems that the engine was rebuilt not long before it was taken off the car. |

Put all my flat screwdrivers away so I won't be tempted.
Tried to split the case and lost the first battle. Any easy way to split it? I don't have the oil pump splitter, can I do it without it? |

Chances are you missed a bolt or two.
The case really comes apart easy once you find them all. I used one of those soft jaw woodworkers clamps that you can operate in reverse and pushed the two halves of the oil pump hole apart. I couldnt get apart and wasnt about to pry (like the PO), so I kept looking for more bolts. Once I got the last one it almost fell apart. Stu |

I already broke one clamp this morning. Found 2 more but still no joy. It cracks on the oil pump side but only there. Any bolts behind the flywheel? I still have it in place. |

Good luck, Terry Not to be a prick , but how many have you taken apart? I have seen way worse looking aircooled motors that ran.... This motor looks pretty average, except the poor handling of some of the parts, and oil pump...overall it looks like any other oil covered type4 motor after some age. Rich |

Yep, there is one below the crank under the flywheel. Gonna need to yank the flywheel. Where did you get that cool billet engine stand adapter? |

Pull the flywheel. There are things behind it you need to remove. Zach |

Buy my damn video!! I go over every nut and bolt thats required to disassemble the engine. lots of cases have been wasted due to a single fastener that was left in place when "I have removed all the nuts and bolts" wasn't really the case.

The last engine case we split had a ton of sealant between the halves ... it was a bear getting it to come apart, and after we did, we found lots of sealant 'slag' inside (IMG:style_emoticons/default/dry.gif)
