I have done this so dont yell.
Assuming you have a broken valve spring, or a dropped seat. You will need to replace the head and the piston. If you do what I suggest, you will certainly need a piston. You can pull the adjuster so the valve never gets compressed. Pull the FI electrical. Remove the spark plug wire. Drive it home. You can pull the motor and put a new head on it and put it back in place in a day or less. I may have a head, if not someone around here will. This would be easier in a garage with jack stands, but it would also be possible (I know Dr Evil will smile here) on the side of the road without removing the engine. Remove the HE, drop the motor down on one side and remove the head. It can be done...those are the short instructions and you would need help getting it done right and quickly... Start begging for help. Rich |

i am still a newb here. Thanks for the advise rich.
I actually adjusted the valve to .006 and fired it up and let it idle for about 15min. it still has enough compression that pulling the injector lead made the engine studder noticably. If i have lost a valve seat, why when i search do i see so much carnage, and my car is actually running the same as it was before this incident? since i adjusted the intake the sound is gone, and i even took it around the block 2 times with no problems. am i playing with fire here. Mabey it is not the seat? (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/blowup.gif) |

You have got crap compression on the cylinder at 65% leak. You can drive it on 3, as Rich says. if the valve seat is failing, it will fail faster if that part of the head gets hot, which it will if the cylinder is firing. If the seat falls into the motor, it will get unpleasant rather quick, and it would be best to avoid that.
I am free tomorrow (saturday) morning. I can follow you down to Fells with tools, and chase you back home. You can put the car in my garage for a short period of time - not longer then it takes to close on your house. But you can store it here short term. If this is somethign that you want to do, call me tomorrow earlyish and I will swing over and get you. Let me know. Zach |

Mabey it is not the seat? (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/blowup.gif) When a seat drops, it is no longer tight in its position in the head. It can drop and be crooked holding the valve open. It can also drop back into it's position and seal somewhat. This can repeat over and over. Sometimes it will seal and sometimes not. I had this on a 2.0 that must have gone on for quite a while. The spot for the seat was worn huge! this did not happen overnight. |

(IMG:style_emoticons/default/beerchug.gif) I did not have time to get it home last night, I will be attempting tonight about 8pm. I will pull the injector lead and run nice and slow, and stop to check the valve a few times along the way. I will let you guys know ... hell if i can drive it 60 miles with no clutch (IMG:style_emoticons/default/chair.gif) this should be a cake walk (IMG:style_emoticons/default/blink.gif) |

I cannot fix my car now, because my garage is in boxes and i am soon moving. Wife said engine drop is no longer allowed until i am in the new house (IMG:style_emoticons/default/sad2.gif)
however i did get a pic today. if you look you will see the intake on #1 adjustment is now flush with the nut. but at TDC i still have .006 on both valves (IMG:style_emoticons/default/confused24.gif) now i get to wait. Attached image(s)

I'd bet it is a dropped seat.
The seat came out of the head and moved in towards the case. Ken |

QUOTE(jsayre914 @ Jan 21 2010, 12:40 PM) OK i rechecked the valves, alls well. I pulled the air flow meter open, everything was perfect inside, as far as i could tell. I then squeezed the spade terminals a little bit snugger at the dual relay, and cleaned all the connections. Ran the same (IMG:style_emoticons/default/dry.gif) THEN..... (IMG:style_emoticons/default/blowup.gif) All of a sudden the loudest banging you ever heard comming from the driverside valve area (IMG:style_emoticons/default/headbang.gif) WTF happened. Car will not idle now and i dont even want to start it untill i have time to pull the valve cover and take a look.

I'd recommend doing both heads at the same time.
In case the other head is ready to do the same..... |
