Need some help as usual.
I have been reading many threads and diy's for a very simple question. I have read the MB shop manual and failed to find the answer. I need to know if you are to introduce the IP at TDC or at 24 deg. before TDC. After the third time using various methods of "drip/sec." and from 24 to 26 deg. BTDC, I have the same or worse results. Results: Painfully slow 84 126 Turbo car. Can't drive even to parts house. I have called to some of the mechanics on line who would not talk about the IP. Called local shops and got some theory but no one who will speak definitively. Those who did speak have lead me to try twice more with worse results. No, I won't tell you what I have done up till now. Why scramble the maze.

I have set the IP with the notches matched for #1 ready on each attempt. Fitted notched collar and introduced IP onto studs for adjustment.

I have tried various drip formulas and each time have this painfully slow 126.

I have read about tank filter etc.

I just need to know at what time to introduce the IP.

The answer must be so elemental. All I have read would lead one to introduce the IP at "begin of delivery" time. (24 deg.BTDC) Why do I have to ask about inrtoduction at TDC? Because the last two tries have the same poor result.

If someone with real experience and no theory could please inter the discussion I would be grateful and will answer your questions.

Thanks for all, LD
