Question BIGGER Problems

Thanks for your help marti5! I got the old water pump out by using a c-clamp the banging on the clamp w/ rubber mallet...My engine is an M42. After head gasket replacement and re-installing cylinder head, it feels as if the valves are contacting the pistons and it will not crank over by hand. Before removing and replacing the head, I made sure the cam journals were lined up, arrows on cam sprockets pointed up, notch on harmonic balancer lined up w/ arrow on block and cylinder #1 was at Top Dead Center. But obviously something wasn't right! Any ideas out there?

You must get the camshaft alignment tools (kit) to properly time the cams and crankshaft.

I was going to take the head back off & try again. Where does one find the alignment tool or kit you mention? Bav. Auto? I was positive the cams were correctly aligned. Damn!

sounds like you are 180 degrees off....that could cause that....try removing the timing belt and redo the timing and make sure that the rotor is pointing towards the #1 wire. it's good you realized this by hand. congratulations on that one....alot of people will test by starter motor and toast the whole shooting match.....

it appears clear that you don't have the engine timed right....the cam is not aligned with the crank shaft. that's not a hard thing to fix. however, are you absolutely sure that the motor will not turn by hand? does is lock and you can feel and hear the contact, cause sometimes that's confused with normal cylinder compression. I would remove the spark plugs and try to turn the thing again...if it still won't turn then back to the beginning of my speil....

Angry Silversled, whats your problem!!

Silversled, don't give advice on something you don't know about. The M42 NEVER had a timing belt. Its chain driven. How can you give advice? People like you give your two cents and probably cause catastrophic damage to others. You can buy the timing kits at E-Bay:

Thumbs down Rotor/Timing chain

Silversled. Your are right that it does not matter if it has a chain or belt. This just tells me that you are not familiar with this motor. Also where's the rotor you say to line up. It has a coil pack, no rotor! Hopefully this poor guy did not spend all day looking for the rotor to line up. Hopefully you did not waste any more of this poor guy's time Point is, I don't think you are qualified enough to give advise on this particular engine.

As a certified ASE/ BMW professional it make a tremendous deal to me what drives to cams. Other BMW professionals would probable agree. With a attitude like yours, i assume that you are not the type of person who likes to get the job done right the first time and don't mind reading inadequate information or directions.

Well, you know what happens when you assume hun , It makes an @$$ outta You and me. You said yourself it doesn't matter what is driving the cams. BTW I have been working cars for years. I am currently working on becomming an ASE Master tech. The message I'm trying to convey is that you should know a person before you go around assuming Incorrect information. If you would like to actually get to know me before spouting off PM, Email[My username @ yahoo.com], or AIM[sk2boi] me.

To the Original Poster,
I would recommend buying this " BMW 7 DISC SERVICE SET:TIS,WDS,KSD,EBA,ETK,WDS MINI,ETM - eBay (item 270336810226 end time Feb-07-09 11:49:34 PST) " I just bought it, It should arrive anyday now. I used it before and, it had very good instructions and has every spec on the car. I have not worked on the M42 but it shouldn't be to different then any other DOHC engine.

Thanks
~Alpine

Lightbulb Long way to go.

AlpineSixAndSeven. You have a long way to go in this business. I do respect your input though. You are very knowledgeable. An Internet engineer. How much real world experiences do you have working on BMW's.

EEEASY fellas! Remember- we're all on the same team here. We all love our cars and work on them because we like to. But just to sum things up... The spark plugs are still out, intake & exhaust manifolds still off. Everything you remove to replace the head gasket on an M42 still off. So far I only have the head back on. When I removed it I secured the Timing CHAIN to the cam sprockets, #1 cyl @ TDC, cam journals lined up correctly, tool through flywheel etc. It WON'T turn over. How could I have gotten 180 degrees off? That seems logical, given what it feels like but.... how?

Did you use the tool to lock the cams into place?? Did you remove the timing chain's primary tensioner(round one)?? These are vital steps to timing success.
