While I'm sure adding Locktite 518 is an ok practice, the only thing the Orings need is a bit of oil or light grease. Same with Pushrod tube seals. I use some added dirco to the cylinder base but it's not necessary. He'll be just fine. |

Yep, Oring + petroleum product will seal well....
But Oring with a proven sealer compound will in all probability seal better and for longer.
Hopefully he didn't slip in the Orings dry.

I totally agree.. A little lube makes everything fit better.
I actually think that is the benefit of 518, it appears to create a slimy film that doesn't wash away. I have worked on quite a few vans with it slathered all over the place due to some recommendations on here.. Don't understand using it on fuel line connections.. Just sayin. |

| Oil pump lost prime. Quick shot of air in the dipstick tube from your compressor while turning it over will take care of it lickity split.. No sh.. |

No oil pressure? That's a major bummer!
I hope the air trick works for you.
You ground the pilot bearing down?!?
Metal Doesn't shrink like that, there's a bigger problem you masked over. I hope it doesn't come back to bite you.

| Just in case this doesn't work. Any other way to prime the oil pump? Was there a way for me to avoid this during reassembly? Something I miss out? |

Haven't had to do this on a WBX but on other engines I have packed the oil pump with Vaseline to help it get primed at initial start-up. |

spin the oil filter loose, then crank. When you make a mess, tighten it back up and crank for pressure.
Worst case remove the filter, and pump oil into the center part of the filter adapter, while rotating the engine backward by hand (to prime the pump gears).

All good tips.....
Here's mine: disconnect the coil from the distributor so that you can crank but not start the engine while circulating oil/verifying pressure.

Thanks T3 Pilot,
I had done that (crank with disconnected coil) prior to starting the engine for the first time. I cranked for like 30 sec.
The engine actually run 4 time 10-20 sec each time trying to get/measure pressure. Hopefully no damage. I hope this bearing guard grease was good enough to lower the amount of damage.
I will try the compress air first thing in the morning. Then I will move on to the oil filter ideas. |

jberger!!! You rocks!
A couple of small air shoot while crank and it quickly builded pressure again. Wow..
Now I think the lifter empty out while I was trying yesterday because the engine didn't sound that great at first. Cyl 1 sound like it's got a lifter not totally pressure up. What would be the best thing to do to get it good. I'm still in the coolant filling (3 gal out of 4) part of it before I try breaking in the motor. I would tend to run it for a couple of minute until the clic clic end up and then readjust the valves rocker before breaking in. What do you think?

| I still have that clong-clong noise after 3-5 minute at 2000 rpm trying to get the coolant purge up. How long should I expect to run the engine before the lifter noise go away? Should I re-adjust the valve? after a certain amount of time maybe? |

Every engine is different. I've had some lifters pump up very very quickly while others can take as long a 45 minutes of driving to fully quieten down. |

| Ok! run it for 5-7 minutes this morning at 2000 rpm to finish the coolant purging process and the ticking was a lot better right off the start. I will now adjust the the valve rockers and check all the lifter are hard and nicely primed. Then I will break the piston rings and lifter procedure by going on the road at high rpm and on hill climb at high RPM as suggested by Dave. |

I did as best as possible to break the rings and new lifter in as Dave suggested. Then I drop the oil while the motor was still hot and filled it again.
Two thing are worrying me at the moment. There was a serious constant hissing noise at high RPM (3000-3500). That would go away when I pressed the clutch. There also is a bit of oil dripping at the front of the engine. I'm afraid that would come from the flywheel seal area. What do you think?
Other than that there was good power and an ok engine noise. I will let it sit until tomorrow for the pistons and rings to cool all the way down. |
