That's a nice kit. Who makes/sells it?
Congrats on job well done. |

The spring compressor was off Ebay... I looked and the same one is marketed under a few names. Kinetic, or Schley or JTC, but all the same.
I think I paid about $50. The two black towers fit on two of the cam towers, and the long bar goes in to them to act as a leverage point. We used the holes either side of the center. The red handled lever arm goes under this bar and the spring hold down goes in the first of the 5 holes. It works great! The best moment was when we realised that you cant pull down on the exhaust valve springs on #5 & 6 because of the firewall/battery tray area. We reversed the spring holder into the hole right on the opposite end and pushed up to compress the spring. You have to be strong tho!

So we did the Stem seals but the misfire was still occuring.
After some testing with my dad (Merkey) we established that there was no electrical connection on the ignition wire #1 and so we used a makeshift spark plug from one laying around and the misfires instantly were reduced to a small shake. So we thought that this was the problem all along and the last few misfires were most likely coming from the other plugs. So today I purchased a brand new set of Bosch Ignition leads and hooked them all up and the misfire is still there....GRR!!! Also, on spark plug #4, I can hear ticking, or the spark...so we were thinking and it could have been possible that we mixed up one of the small little metal things on top of the valve's when we replaced the stem seals, because I know that we mixed them up (they looked identical so we just guessed it would be ok) ^I dont know the name of it....its silver and is between the clamp and the valve. You can see a shine from it in the picture....thats the thing. Grrr...Could the last misfire be coming from that ticking spark plug #4? Could the distributor be a possible problem? Also on a side note, 2 weeks after doing the stem seals, I checked the spark plugs and there is 0 deposit So the job was successful.

No, the valve shim directly under the rocker ball that bears on the valve tip.
Am I correct in saying that the valves have hydraulic lifters and therefor need no adjustment?

Just to do an update to solve this misfire:
We did some tests on the spark plugs by pulling them out and there was a really weak spark on plug #1 (I am assuming that is why it caused the most oil on that 1st plug as opposed to the rest). So then we used another spark lead and it was MUCH better. So then I went out and replaced the whole set with some brand new Bosch Ignition Leads. This made the shaking considerably better and there is no longer any chance of stalling. It IS still there though and you can still feel it quite reasonably at idle. What would be the next step into finally resolving this horribly irritating problem?

Bump.
Just ordered a set of NON-Resistor spark plugs. Could this possibly be the solution to fix everything? Or do you guys think this will just help?

Ok well with the new non-resistor spark plugs in, it feels very slightly better, but that could be just placebo effect. Either way, problem is not solved.
Anybody help with the next step we should take?

Since you mixed up the valve shims, which are different thicknesses to bring the hydraulics into range, you may have a valve opening late or not closing fully.

We looked at the shims and they looked like they were the same thickness and our car utilizes hydraulic lifters, so therefore it should not make a difference if they were mixed up.

If we are talking about these They come in 1.5, 1.8 and 2.2mm to compensate for differences in rockers, cam lobes and such.

The ones we pulled didn't look like those (they were circular with a circular indent in them, like a bowl). We put two of them side-by-side and the heights and width were identical.

Hmmm,
I've never worked on a 300TE engine so I believe you, just be thankful you don't have a M117 with it's 8 different sizes of shims to keep track of. Michael

Also I was told that the O2 sensor cannot be our problem as it is not used when the engine is cold and my misfires happen right away cold or not.

I just finished testing my injectors....
Each spark plug that I pulled separately made the misfires alot harder and each plug removed causes the same amount of harder misfires. Does this conclude that the injectors are not the problem here? As I said also, the previous owners said they had the injectors replaced. What is next to test?
