M20 45mm welch aka core plugs (DO NOT USE FEBI)

It swaps out and works perfectly fine, I speak from experience.
I was experimenting with locks on my own as I didn't see that writeup when I did it. Therefore I wasn't aware about the inner plate...

there is a check panel on your ceiling that has BIG button called CHECK. Dash light flashing basically tells you to check all the info on the Check panel. You press CHECK, whatever stays lit on the check...

here is what I came up with. I didn't want to braze the oil return line on the dipstick tube as it would require painting the whole thing. Also Didn't want to separate the dipstick tube 325iX style with...

I think that cover should work on late cars from what I've seen through years. Does the injector harness rail actually block the port or the hose just has the wrong angle? Hard to see from your pics...

Im in the process of rigging up the oil separator from S62 p/n 11151406789. Basically want to make similar arrangement to S14 oil separator where its going to vent into the back of ITB airbox and drain...

any comments on this? There is no vacuum in the crankcase on M20 because it wants before throttle plate? Am I correct?

[zaq123]

yes its good stuff. Its actually the same price per ml as Loctite but you won't find lactite in small quantity, the smallest is 250ml...

45mm brass from them is almost 1/2 the price of OEM steel. Loctite 540 is crazy expensive too so if you need just for one block, I'd consider Vibra-TITE 550

It's a gamble. New plugs can leak too as you can see. Looks like I got a few bad brand new ones when I did my block. Now it looks like there are no longer good ones from Febi at all. I actually ended...

Tanking M20 block is no go unless one has a plan to replace the intermidiate shaft bearing which is a pain and I wouldn't do unless the bearing is shot. But I'd replace them plugs for sure. Wish I'd inspected...

plugs rust on the inside so it hard to tell their condition. Additionally, once you bore/deck the block. all that crap is gonna sit everywhere and it's easier to clean the block with plugs out....

e30 as many other BMWs have drivers door lock setup for a double lock feature. Basically if you double lock (turn key in drivers door twice) it prevents opening doors from the inside. Silly anti-theft...

[zaq123]

any guesses? I tend to believe it's more of a complementary but wanted to see if anyone knows for sure

[zaq123]

unfortunately I didn't see it. Now paying for it. Decided to pull all 11 Febi plugs out because I don't want to do it again ever again. Major pain to do with the engine in the engine bay. Especially that...

Just a word of caution, do not use febi Welch plugs when rebuilding your engine. I built this stroker a while ago and used Febi plugs ($1 vs $10/each for OEM). One started to drip so I pulled it out,...

Which type do you think it falls under:

Uni-Directional - Both outputs will have the same duty. i.e. When the Main is 25% the Slave is 25%.
Complementary - When one output wire is increasing...

[zaq123]

exactly. Yes they are $5 each for whoever unknown reason but $20 will be well spent, trust me. The part number I listed is made for your rocker shaft...

very old post but I found it because I had the same issue. Here is a resolution. Check your new fan (yes even OEM) because in it's C113 connector, High speed and Low speed wires were reversed. Which made...

Also related question regarding How crankcase ventilation is designed on M20. Ok so there is a drain tube between the head and the crankcase as well as oil drain holes near cam rockers in the head. Valve...
