Didn't fix it the ticking... Here's a video of the noise in question: http://www.viddler.com/SomeGuy207/videos/1/ Anyone know what it might be? (Please forgive my horrible camera work.) |

Well by work I meant upgrades, so I'd like to keep the head if possible. Now I've also had someone suggest that the ticking I'm hearing may be a rod bearing on it's way out, and I've read that the main reason for bearings to fail is due to lack of lubrication. But I've never once run this engine low on oil, and I'm sure my friend hasn't either. | ||

Noticed it last month before I went to adjust valves since I had some ticking in the head (which went away after adjusting valves) so the ticking I hear now is more noticeable. Last thing I've done is adjust the valves (Twice just to be sure I didn't mess up somehow). 5w-30 full synthetic. Will do, I'll call him when he gets off work. | ||

IDW God Member Group: Members Posts: 196 Member No.: 16,620 Joined: Mar 14th 2006 Location: Florida | Well, I read this guide a bunch of times and followed it: http://www.c-speedracing.com/howto/valvead...valveadjust.php But I went to skunk2's website and looked up the valve lash numbers there and set them to those specs. After each valve, I double checked the lash just to make sure the screw didn't move while tightening the nut. Will try new oil, should I stick with synthetic or use regular? |

Stick with synth, you shouldn't need dino. | ||

IDW God Member Group: Members Posts: 196 Member No.: 16,620 Joined: Mar 14th 2006 Location: Florida | Gotcha, but looking at valvolines website, I only see the synthetic go up to 10w-30. Would that suffice? |

M1 sells 10W-40. I'm not sure if it's a national wide thing, but Advanced is having a sale on cases. | ||

Snooping as usual Group: Advanced Members Posts: 1,780 Member No.: 32,588 Joined: Apr 13th 2009 Location: what are you doing in my swamp? | Damn, I feel like a bit of a cock for suggesting an engine swap. If it makes you feel any better, from the video, I don't think that sounds like a bad crankbearing. Having torn one to shreds, I know what it's like. If it's on the way out, it'll cause huge vibrations when you try to start it. You might have a clogged oil passage somewhere causing the Valvetrain to be under-lubed. Gunk buildup is no fun. |

It's ok lol, but how would I go about unclogging them if they are clogged up? Is there some sort of additive? This post has been edited by SmGy on Apr 30 2010, 02:27 PM | ||

Do you have an oil pressure gauge? Check that first as that'll tell you if something is off. | ||

Snooping as usual Group: Advanced Members Posts: 1,780 Member No.: 32,588 Joined: Apr 13th 2009 Location: what are you doing in my swamp? | They make a product that you dump in your old oil, idle the engine for a couple minutes, then change it out. I'm not sure how far I trust that, though. If your car has had regular oil changes, I don't really think sludge buildup will be a huge problem. I'd just change to the thick stuff like Floh recommended and be sure to get a new oil filter. Change it immediately after you're done driving it, when the oil is still hot, that should allow most of it, and any thicker parts to flow right out. If the oil change history is questionable, go ahead and try the solvent product. Waxes in the oil tend to harden, and that's a large component in sludge. Synthetics don't really wear out the same way dino oil does, and they stay pretty homogeneous, only problem is the additives get used up, so you still have to change it. Side note: I wish I had an oil pressure gauge. That'd tell me how thin I can go. My guess is my car will probably only work on 40w90. This post has been edited by Cactus on Apr 30 2010, 02:45 PM |

IDW God Member Group: Members Posts: 196 Member No.: 16,620 Joined: Mar 14th 2006 Location: Florida | Guess I'll need to grab a oil pressure gauge tomorrow too. I've kept up on oil changes since I've had the car, and he changed it before he sold it to me almost two years ago. He's the one who told me to use the 5w-30 full synthetic in the first place. |

O'Reilly is too. Shit's cheaper than it's been in years. We also just got in stock a house brand synthetic, which is the same quality as all the basic Valvoline/Castrol full synthetics. If you really want to make noises go away, Shell Rotella T 15w-40. This post has been edited by cmspaz on Apr 30 2010, 10:02 PM | ||

BMW M20 engines' default noise is CLACKCLACKCLACK. Then again, I think the only real cure for that would be gear oil with some ZDDP in it. |

IDW God Member Group: Members Posts: 196 Member No.: 16,620 Joined: Mar 14th 2006 Location: Florida | Sorry for the late reply, never got a chance to change the oil until yesterday. After using the new oil, it seems the ticking isn't as loud as it once was, too bad I can't tell for sure since the car doesn't get a chance to warm up thanks to my ignition switch going out. Car won't even stay started for more than a minute... |

I'm not even sure an oil with a high ZDDP content would even help it, since the zinc and phosphorus act as sacrificial items to help PREVENT excessive wear. After the fact it'll just help with future wear. I would personally rebuild the head and spec everything to see if you can find the culprit. Also pay attention to the oil that you pick in the future (personally I use Amsoil) . Here's a great article on the topic. http://www.compcams.com/Community/Articles...sp?ID=945638917 | ||

My engine is pretty damn healthy for a 140,000 mile piece. Freshly rebuilt M20's still sound like diesels, it's just the way they work. |

My apologies. I was actually agreeing with your point on a high ZDDP content oil in relation to addressing the OPs issue. I should have read your post more carefully. | ||
