damn, looks like they have seriously been flycut...
Anyway, I thought I saw signs of a piston bumping against the head and thats a sure sign of a wiped rod bearing... But it appears to be okay.. |

Yep, watch the video...
Normally if a pison bumps into a head it is very apparent, more than what I see in the pics.. One thing is for sure- It was running rich.. Rich= fuel contaminated oil..... Fuel contaminated oil= Spun bearing WAY faster than normal.. Check journal #2 for a bad bearing first, its the first to go if you have an oiling issue, it gets it's oil last and not quite as much of it generally, especially at low RPMs with heavy load... #4 is next to go so check it too... |

It ran rich alright - for years - on D-Jet So do you think that maybe my "rich" d-jet could run my new 2165 w/out a lean condition? It's got a mild F.I. compatible hydraulic cam & lifter set.
Uh Ohh, I said hydraulic & d-jet (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) |

The problem with FI and larger engines is they simply try to lean out at peak torque- right where you are typically cruising..
D jet with the delayed valve events of a hydro cam would be pretty much a recipe for a nightmare IMHO... But if you tossed the brain for a programmable modern system you could preobably pull it off easily, even with stock injectors... Why the hell are you going to use the hydro cam?????? I have an M59 fragmentation grenade that would probably be just as effective if you pulled the pin 3/4 the way out and zip tied it to the valve cover bail... Seriously, you are going backward explore the possibilities of solid lift closer. |

what is that in the second picture left cylinder upper right of the intake valve. looks rough, is it ? something beating around on it? a bent valve or debris. hows the piston look on that cylinder?

I see what looks to be a big hairy-ass crack (not to be confused with Z's big hairy "ass-crack") between the exhaust valve (left side) and the sparkplug hole......but then again, I see them everywhere.....ALL of my 2.0L heads have them (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)
