hey guys, i hae this annoying noise that i could also hear while in my car. is it normal? i do have 159000 mile on m car. on the video of where im pointing at is where it is loud.. keep in mind, i alrady changed out my belt, tensioner, idler pulley, sprag bearing. maf, water pump ... car feels a little laggy at times. like the car just feels like the rpms are. throttle response not responsive and did the reset already. i feel like im missing out a part to also replace due to high mileage.

The lag means you need the crankcase breather hose repair kit. When was it last done ?

pogijeffrey

havent done it


where would that be located at ?

to describe what im talking about is that the car feels heavy when i step on the gas and seems like i waste more gas at times because i step on the pedal harder than i use to. it doesnt take off like it use to.

There are hoses and joiners all over the place. Weaving its way between the manifold and the cylinder head is a 1/2 inch hose. Squeeze it and if it feels hard or mushy its gone bad.

There is also another hose between the rocker cover and the intake manifold.

This is a 4 or 5 hour job. You need to loosen the intake manifold, use a hoist and also replace the coolant link as it normally snaps when touched.

Look at the attached photos when I did my friends overhaul.

Covers off, airbox removed.



Parts kit
* Valve
* Crank hose
* Cam hose
* Elbow shaped hose
* Joiner hose to valve
* Special preset clamps (avoids over-tension)
* Manifold gaskets
* Fuel injector O-rings if you dismantle the fuel rail.



Coolant link always breaks (very cheap) Left side of engine

The end result was a massive improvement in fuel economy and significant torque improvement between 1000rpm - 2000rpm (below the supercharger cut-in).

I was using 98 octane fuel and I reset the engine controller with the diagnostic and cleared the learning. I made an ignition correction by specifying only 93 RON fuel and higher.

thanks man... i highly appreciate all the help... so how much does a repair job like this cost, labor i mean...?

pogijeffrey

benzmod,
u think you could provide me part#'s for all parts needed to replace.

i already replaced the coolant hose connector. it leaked a month ago

benzmodz

I will try to find the paperwork. The list was comprehensive and may be more than your mechanic will use. Though I hasten to add that the parts are included for a reason.

Labour should be 4 hours.

When I find the list I will post it.

Thanks for the help. I have another issue. My car is completely back to stock, issue I'm having is vibrations on the steering wheel at speeds over 60mph. My stick wheels have brand new tires. The car is aligned. I can't seem to Catch a break. My lower control arms were replaced few months ago along with new tie rods. I just want my car to be smooth again. I'm definitely going to check out all my breather hoses and get them replaced. Hope that fixes the somewhat lag.

benzmodz

Given your mileage, vibration at speed is usually bearings as you appear to have done everything else.

Did you also replace your thrust arm bushes and camber bush ?

If your looking for the 12 dollar hose replacement. A 203 018 1282 is not valid no more. They change the hose again. I was there this morning trying to get another hose. while my engine is apart for timing chain. I didn't have time to wait around for the girl to search for the new hose part #. I just ordered my other things and left.

benzmodz

I bought 12 82, try this part number.

A 271 018 12 82 Breather hose - all engine parts start with engine number.

Good luck with the breathers. I think you are on the right track.

Can you post that video again but get someone to rev the car up from idle a few times.

Have a decent roadforce wheel balance done. This is not the first time you have suffered shakes.

benzmodz

I wonder if the engine has the spacer harness on the cam adjuster installed.

pogijeffrey

How do u know when to change out timing chain?

benzmodz

You just look at the teeth wear when you take the rocker cover off.

pogijeffrey

If you are talking about the extension harness connected to the cam sensors. Yes, I did... But if your talking about something. Please describe an let me know.


Thanks

A 271 018 12 82 - i got this hose from Autohausaz.com - it recently broke on the crankcase end because it had been attached with a screw clamp - the clamp seems to have been overtightened and cut right thru it. Managed to reattach i after taking out the piece that broke off, but I am about to order another one. replaced the clamp with a squeeze one.
