URGENT HELP! M42 engine question (whos got a block with no head on it)

[Snowmann]

I need to see pictures of the non-return valve in the block - according to Real OEM its on the Pass side center between 2 and 3

I never removed it from the block - but now that the motor is back together I am questioning whether or not it could have fallen out while getting hot tanked...




However in this picture I cant see how it could be there as its the threaded hole for the head bolt only... Is it installed on this picture? anyone know I dont ever remember seeing anything like this

Help I need to know ASAP so I can order parts if need be it

I've got pics of an M44 comin' to ya.

[Snowmann]

I dont need the block but can you see what the deal is with the check valve? where it is - how far down into the block it is - is it a tight fit - is it a loose fit

[Rob]

i know how to fix it....install a real motor?

[Hick]

WTF are you talking about?!?!

see 10 and 9

i never removed them as i didnt know of them so im affraid now that during hot-tanking they could have fallen out or are shit now

any ideas? my block looked just like the above pic when the head got bolted on so i have no friggen clue - but then i got a bently the other day and saw this tid bit about this anti drain back valve (check valve basically)

EDIT: Gah my engine got moved. Sorry Chief

[Hick]

Damn, sorry i cant help. I did the headgasket on mine several years ago and dont ever recall a part sitting in that hole. Check and see how the headgasket covers it, if it even does. I can understand the one way valve, but under running conditions i dont think it would effect the lube system. Keep in mind, the only pump is the oil pump, nothing else picks up oil on a motor. Only thing i could see it as would be to have some oil up top for the valves/lifters on start up, but even that isnt being forced in.

If i were you, and im glad im not, id trash the thing. Let me know what bin, when dropped off, and detailed directions.

[Snowmann]

Im not even sure what hole they're referring too - in the bentley its one of those illustrations

Every other lower end pic ive looked at tonite on the interweb looks like the pic i posted above - and thats what my motor looked like when i popped on the head

Im thinking the bastard is burried way deep in that passage and is a fairly tight fit - (once again what im telling myself)

I dont know in terms of oil pressure or anything if it will effect it - I know on some motors there are various needles in an essence that restrict flow to obtain certain amounts of pressure BMW dubs this guy a 'non-return valve' so im going to assume its a check valve

I might pull the head off the e36 parts car tomorrow and see what i find -

the worst part is i know the bastard is gonna be in there - but its just one of those things thats bugging the crap out of me

[Hick]

I think you may of found a place to stick that useless pin of yours.

[Snowmann]

in the hole in the side of the block that is going to be made by a non oiled lower end?

insert sad face now

[Hick]

And then?

[Snowmann]

is this like that movie

and then

and then


and then



NO AND THEN!



im gonna get my arse up early - pull apart my brothers car lol and look inside to see what i find

[Hick]

Yeah, it was the best i could come up with this late. Cant sleep, its sad cause ive been up and running around since about 7am.

There was nothing there when I did my head. Adam told me that valve is in the block, so I don't know if you could still have a problem. I think all it does it help oil flow back into the pan when the car is off, but I could be wrong.
