ok since last week this happend three times. at wot occaionsally white smoke would shoot out the exhaust then after a couple second would go away. It didnt come back for a week until today.


now all of a sudden i get home and go out for a quick 0-60 run with the car. and when i stopped to check the gtime i heard alot of clicking coming from engine. Now all i hear is a very loud click click click sound. more throttle i give its worse and worse.


what is that and is that somthing serious?? and can i drive to shop or should itbe towed.

What year ? Did you Check oil level and when was the last time you changed your oil ? And stop beating the shiit out that car JK

Hercules86

its a 2003 and everything is fine with the car. no check engine... oil is good. i dnt know what the heck happend.

but i do drive it like i stole it. its funny though there so much clicking... maybe a screw loose in engine or the pistons or blown head gasket. but the car still has full power.

Quadcammer

is it a clicking or a knocking?

take a screwdriver or a long extension and try to pinpoint where the noise is coming from.

Could be anything from a bad lash adjuster to a spun rod bearing.

Hercules86

ok your right its more like Knocking.... its coming from beneath the valve covers.

What you have "may" be a stuck lifter. I drive the same way you do. IE I go through 3 sets of rear tires a yr. You can do one of two things. 1. Go to dealer and pay out the @$$, or use this mix and will cost about $60. Change your oil, use 5quarts of 20w 50, 2 bottles of cd3 oil detergent cleaner (in yellow bottle), and a bottle of Lucas oil stablizer.

The oil detergent cleaner will free any stuck valves or lifters. Once u change the oil drive it about 2 days. I did it about 15K ago, never had a problem and haven't slowed down since. Stuck lifters are a common thing. If you don't believe me go to the dealer and tell them to crank up a 2010 model (doesn't matter which V8) that has been sitting for a while, and tell me what you hear.

nice tip thanks. i change my oil every three thousand. but my right valve cover is leaking oil alot... this must be because the gasket is worn out.... ive heard this is a problem on the m113 engines.


i hope its just the lifter... i dont feel like replaceing the engine.. even though a 5.5 upgrade would be nice.


anyways i have a tow truck on its way and its being brought to my good friends shop to be examined... will update shortly

Changing the oil every 3K is mandatory for an Acura that uses 5quarts of regular oil, but for a Benz that uses 9.5 quarts of synthetic, it's more counter productive at that frequency and a certain waste of money IMO.

How many miles on that car BTW? How old are you?

Quadcammer

I'd also be very careful putting 20w-50 and that concoction of cleaners into your engine.

thats a hell of a big risk if you ask me.

Benz5656

Think what you want i'm just giving my advice what worked for me. Its not a concoction its a way of freeing stuck lifters without having to rip the engine apart. What do you think most of these dealers/independent mb shops do. They they can charge you $800 bucks to say they changed out your lifters, and who is gonna take off their valve cover to verify that? (like you could tell)

Hercules86

lol... good thing i did none of the above but thanks for the advice.


the problem was a bad AC compressor.


as soon as my friend looked at the car he knew the problem. he took the belt off and started the car. then noise almost completely went away. the rest of te rattled ws from the ac compressor.


funny thing though is i never use ac.... prob only 3 times this year so far since i like to have windows down... weird how the part that is least used goes bad

Benz5656

Yeah that is funny, but that is how it is with these cars use it or loose it. LOL. But its a good thing it wasn't anything worse.

Hercules86

and my 06clk i drive the shatt of my car and everyone should change there oil at 3000 . have you ever seen the oil at 3k... it real black... and mb wants you to change at every 10k so they can make money on you when you damage your engine., im guessing you change every 10k.. good luck with that.

Benz5656

THANK YOU!!!!!! I have been trying to tell people this for years. Engines are made to last longer, so that means you will not buy cars as frequently. So dealers loose profits. If you change your oil every 10k, over the life of the engine that is the difference in you getting 250,000mi or 300,000mi.

Quadcammer

sigh.

oil is black because of the detergents in it. Black oil is not bad oil. I can 100% guarantee that if you sent your oil to blackstone labs and had it analyzed, they would tell you that its good until 6 or 7,000 miles easily.

3,000 miles has been a myth for a long time for synthetic oils.

Not to mention the 113 is a completely non-stressed engine. It doesn't have overly high compression, it doesn't rev very high, and it makes a paltry 300bhp from 5 liters. There is absolutely zero need for 3,000 mile oil changes.

You are just wasting money.

Before spending $1000 on a new A/C compressor I would take it to a qualified shop and have them check the freon in the A/C system. When these leak and the pressure drops slows, the A/C compressor will make a clunking/knocking sound. Once you fill up the system with freon and compressor oil it should stop.

Hercules86

cost me under $100 for 2 boxes of mobil 1 filter and oil change. i got account at soverign motors. so its def worth it. taking good care of the engine will help its longeivity in the long run so why not especually since i drive the crap out of it.


and the compressor was bad not just the freon... i had new compressor put in and freon as well for $375 in parts and $150 in labor. cant beat that

John Doe

im going through the same thing,i have an 03 w215,the compressor locked last night,the poly belt was rubbing sooo hard there was tons of smoke coming out,then i couldn t even start the car .it was cranking very slowly,my check engine light turned on,this morning,its the freakin cap of the compressor that came off and had 3 connections broken,ordered one for 300 today,the dealer wanted 900 ,they said it comes from germany but then when you look at it,its made in japan ( denso)..lol,i m gonna put it on tomorrow!! wish me good luck
