Car sat for 3 hours to cool before starting.
Find TDC for cylinder #1 (distributor where it should be & mark in the right spot in the fan housing). Adjusted both intake & Exhaust to .15mm. Done Move onto Cylinder #2. Rotate the drivers rear wheel counter clockwise. Find the notch in the bottom of the flywheel. Through the little hole on the bottom of the bell housing. Adjust both intake & exhaust again to 0.15m. Done Move onto Cylinder 3. Rotate the rear wheel until I find the mark on the flywheel. verify I have it at TDC again at the distributor. Adjust both the intake & Exhaust again to 0.15. Done Move onto Cylinder #4. Adjust both the intake & Exhaust again to 0.15. Done (not (IMG:style_emoticons/default/headbang.gif) ) I put my valve covers back on. Get the car back on the ground & fire it up. Runs rough. I shut it off & think (IMG:style_emoticons/default/WTF.gif) did I forget. So I go back through the whole valve adjustment in my head. I think I have this down the farther I got along. Cylinders 3 & 4 went much quicker (IMG:style_emoticons/default/screwy.gif) . Son of (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) . Forgot to rotate the wheel & get TDC for #4 (IMG:style_emoticons/default/wacko.gif) . Guess I feel a little better as it makes sense now. Just feel like an idiot for not catching it before I buttoned it all back up (IMG:style_emoticons/default/confused24.gif) |

If it makes you feel any better, I adjusted mine perfectly a few years ago, then went in and had a bite to eat. Came out and fired it up, it would not idle at all
(IMG:style_emoticons/default/WTF.gif) Crawled under and found both rocker covers still layin on top of the heat exchangers. (IMG:style_emoticons/default/first.gif) |

Where did you get the .15 number? I thought everything was .006,.008 for our engines?
Oh and zero for chromoly pushrods. |

Read the pelican tech article. Question Cap'n ? You said .006 intake & .008 exhaust for a 1.8 & a 2.0. The pelican article says the 1.7 & 1.8 are both .006? Since ill be going back in. I want to make sure I get it right. So good sir what is the right number?
Your method definitely will be easier & makes sense |

I want to make sure I get it right. So good sir what is the right number? Only the sodium-filled exhaust valve on the 2.0 uses the 0.008" spec. All 1.7 and 1.8 valves, and the 2.0 intake, are set to 0.006". There is one reference (I forget which one) that lists the 0.008" spec for 1.8 exhaust valves, but it is wrong. --DD |

Back in the day, sodium filled exhaust valves were widely available for 1.8s and flew off the shelves at rebuild time. Everyone I knew in the 914 biz used them until they went NLA. I often err on the side of caution unless I know they're not sodium. I'll go back and change that in the post.
