Worlds longest Resto, my C2 2.7 19/3/18 Vent guage action

[e30topless]

Si, scrap the old set up, it's fooked

new rings and shells in the new block, stick an 883 on top with the shrick stick and off you go

this turd could be on the road in a week ?

[Jhonno]

Am I missing something here - why will you need another set of rods, can't you just use the ones from the newly purchased C2 engine (or indeed, the whole bottom end)?

Iirc he used M52 rods as they were lighter? Maybe..

[Jhonno]

Good to see you have re-found some love for this Si

[goosiegander]

[suchy]

Good to see you back on the horse Si
Nice update, been spending some down time in the garage

[capri_rob]

Welcome back Simon. Informative update as usual

How would you know? Have you seen it all up close. Its easy to spend other people money when your not picking up the tab.

I try and take the best pictures i can but rest assured i'm on the right track. The original pistons are in better condition than the new set. It just so happens they are all the same size so i've picked the best 3.

I spent wildly in the past and those days are over its time to use the noggin and get the results.

Thanks folks, i could use some M20 rods yes, hell i've probably got 4-5 sets! I went with these M52 rods as they are slightly lighter and it can't hurt. I can't quite remember which M52 they came from i've a feeling they're 2.0 ones

I shall be doing some mock ups soon so i've got some definative answers as to what went wrong and why. All will be revealed!

[Rich320I]

Love reading this thread its better than most books, updates look great, glad to be able to read them again

[rrs]

Great to see you back on this Simon, good luck!

sensible route mate

good to see you back, and posting

Nice to see an update on this Si. I thought the issuse was somthing to do with a dowl in the wrong hole on the new cams??

[Simon13]

Guys make of this what you will, it rained today so while the iron is still hot and all that!


I've mocked up the engine again but only built up 1 pot as such to turn over and have a see




bits all back on for the cambelt.






Same head gasket, but the piston doesn't look to high to me, its at TDC here





So to refresh, theres 2 dowel holes here. There should be only one for the camshaft sprocket. This is the first ever M20 camshaft i've seen with 2. The same identical camshaft fitted to the c2 2.7 touring has only one. So you can't get this wrong as such. Schrick fed me some bullsh!t that this blanked hole is filled in later on and a new "correct" timing hole is drilled. Aload of cobblers

According to schrick the right hole is the bottom and the top was on the one with small core plug in it blocking it off - the engine ran with the sprocket fitted in this position. We can see they're not quite 180 degrees apart.





I've marked the sprocket 180 degrees opposite to the factory timing mark with a pencil. If you count the teeth they're the same number of teeth apart 23 not including themselves. Doesn't look right but i checked it a few times with a rule






So if you look at the above but 1 picture you can see i've fitted the pulley to the lower hole. The one i used originally when the engine wouldn't run, lets call this hole "schricks" and the other hole "mine" so its easy to tell when trying to explain my thoughts!





Here it is in "my" hole. It looks to be a tooth out. This would explain the contact then.............time for the plasticine





plasticine on






Head timed up "schricks" way. So the valves are opening on No.1 and are also open on No's 4 and 5 also. AS i've said before this is wrong by 180 degrees. What the valves are doing should be happening on the chambers where the valves are shut. Anyhow





bolted down, turned it over a few times................








No contact here then, and a good few mm's on inlet and exhaust. Lets try "my" way then.







timed "my" way, valves open on no's 2 and 3 and no 1 both are fully shut. Note the schrick logo isn't pointing exactly upwards - it should







Oh dear, bearly any contact on the exhaust side and the inlet is touching the piston.

So i guess this all proves what we already knew but in the order it happened. Schrick are right i've caused the damage but they've sold me a camshaft that is no use to man nor beast. 2 f**king holes and neither time the engine up correctly.



To be really sure i've done this all over again with another cylinder head and another bottom end





This is a bone stock low comp 325i bottom end with at least 240,000 miles on it. Its in very good condition and i couldn't bring myself to throw it away. Full main dealer history its hole life. The head is a stock 325i item.




Timed up "schricks" way, looks very similar to on the alpina engine








Timed up "my" way. I'm nearly 100% sure that shcrick logo should be dead flat if you get me?! I'll have to time up the tourings engine and take a picture






Again oh dear, no contact with the exhaust plasticine and contact on the inlet again.


Thing is i've been down this route and schrick have told me to shove it basically. but i know i'm right?! I can't use that camshaft so i need another cam, its clear to me that there has been a manufacturing fault with the cam timing holes which has caused this mess.

Do i carry on the fight?! I want a cam thats correct, just like the one in my touring. Theres my proof that shows this one to be wrong.

What do we think people? The kind words spur me on!

[BenHar]

Go back to Schrick with those pictures. See what they say. If they still don't help threaten them with the small claims court.

Ben

[Gortour]

Another stick certainly.
Is it worth a chat with a lawyer? Even just advice from Beemerlad with regard to compensation from Schrick for you. All the money you've spent on this engine all gone up in smoke because the cam was manufactured wrong, if I'm reading this right.

[bss325i]

Have you spoken to Neil?

[e30topless]

Si, you got a few pics of the cam cog with the timing marks lined up to show the cam/valve position on both dowels?

No 1, and 6 inlet and outlet should be closed totally if correct

would be interesting to see where the cam is at on both holes when it's lined up with the marks maybe shrick fooked up here big style

[Simon13]

that can be arranged. I've got photos of my touring engine like this also to compare

[appletree]

I'd send them the pictures you've posted there and get there opinion, can't see how they can say you've done somthing wrong when the part they have supplied is not fit for purpose.

[Dezzy]

I would hate to deal with this Si.

If the cam has coursed all this damage (it looks like it might have). How do you go about getting full compensation?

The total cost of the damage is almost impossible to put a value on.

[BenHar]

But they could at least give you a correct cam.

Ben

[Speedtouch]

Then they'd be effectively admitting to a mistake on their part!

[BenHar]

Then they'd be effectively admitting to a mistake on their part!

And why not? Do you think they are crooks? I thought they had a good reputation and would want to maintain it.

Ben

[Kedge]

And why not? Do you think they are crooks? I thought they had a good reputation and would want to maintain it.

Ben

But that could leave them open to Simon being able to make a legitimate claim for them to foot the bill for all the damage the cam looks to have caused, and rightly so.

[BenHar]

Twould be interesting to buy another cam from them and compare them.

How much are they?

Ben

[Simon13]

i have this very cam fitted in my touring! iirc the cam cost about £380 plus the valve springs, which were about 6-7 each and you need 24. So it was a fair old outlay for this lot.

[BenHar]

If you've already got one, then just compare with that.

I don't see how they could argue against evidence like that.

Even if they say you should have checked before fitting it they should still supply a new, correct one.

Ben

[B7]

Good to see you back on track Si. Stick with it with cam complaint.

Ben

its fitted to an engine, i'm certainly not taking it apart to try and prove this

[BenHar]

But wouldn't a picture with the rocker cover off prove it?

Ben

[clarko74]

Good to see you back Si.

Which Shrick cam is it that you have? I have a 284/272/110 that is currently tucked away in my garage waiting to be fitted into a head. I could dig it out and take a few pics of it if it would be useful?

[DanThe]

IMO, if one of those holes is in the correct place then you dont have a leg to stand on.
But if they are both out then the cam is as you say useless. You need to compare the holes to the lobes on that cam and another to be sure

[Gortour]

Sorry if it's a daft question, Simon, but do you not have any photos of when you built the Touring engine?
The job you're doing this time is fabulous in its detail. If you did similar last time, maybe there's something there.

[Simon13]

if you guys are still not convinced then i need more photos showing my point.

I'll fit all the rockers into a head and see what valves open and how far in both positions.

I've found a photo of the touring head upside down at TDC, plus a picture of the the valve to piston clearance

[Simon13]

That would be good please Ady, showing the end where the cam sprocket fits and how many holes in it would help my cause! Part no. stamped on it also

Would you sell it if shcrick still tell me to shove it?

[Simon13]

Cam is going back to schrick for them to test it. Fingers crossed eh? I'm fairly certain, i hope they are
