Speculation: How long would it take for a bad HG/head to show itself?

[genphreak]

your not helping without posting more details man.

Dude, Jeff is right- careful bleeding is assumed on an M30, he's right to be concerned. If you are losing coolant, its exiting somewhere. If only under pressure its possible that it is not taking in much air, but it will take some, this is almost a definate- u sure there is not a bubble coming out of the bleeder when u follow the correct bleeding procedure?

I just know you have been around a while, figured you know this from previous posts...

Thing is, I don't have the resources to bleed the coolant system at school.

There is not a lot I can do at the moment, hence: speculation.

Hmmm Are you sure- we don't mean draining it.

You only need an 8mm spanner, the hood open, the correct procedure adn 2 minutes.

If filling the system as you are, its something you should do every time, engine cold and cap off- then tell us how many bubbles come out. This will tell you much, and if you're motor is ok, may return you to normal operation anyway- are you sure you do not just have an air-lock in the top of the head?

Yes.

Really, thanks for the advice guys, but I made this thread intially about HG concerns and it's tracking into basic car maintenace.

You haven't even stated anything about HG symptoms except getting low on coolant which could and can be directly related to basic car maintenance.

You also stated that you overheated the engine a shitload of times (way to far) and didnt bleed it at all let alone correctly...dont be going to sheep now man!

What we need to know you havent or dont want to post which is any of the other symptoms...if there are any at least.

Sheesh this is like talking to the 1st ex on court day.

Yes.

Well I guess that's 'spraying it as it is' Jeff...

Come on JAP, tell us the outcome- don't just leech us for a rundown and close out on us.

We wanna know, is she alive or is she dead? Is she gonna go? Will she make it to ur folks place? Have u got an 8mm spanner or should we post you one Nick

The whole thread is just speculation man, I simply wanted to know if there was a good chance I damaged my HG/head a few months ago and have it only appear now.

She's alive and running fine, she'll probably eventually go, she will make it to my folks' place, I do not have an 8mm spanner.

Lol...FWIR, there's one in the trunk tool kit, if it's still there.

Nick -- JAlfred's too busy scooping the honeys to be working on the car...at least, that's what I'd be doing were I in college

I am probably right in saying the number one killers of M30 heads are air-blocks.

Before you drive it any further do one thing and one thing well. Know the bleed procedure; Without the motor hot or running take the cap off and bleed the system by undoing the bleeder screw on the water neck. Let about a glassfull of cold coolant mix out to be sure. Check it again once warmed up (and system pressurised), letting out any more air- this time you will get air more or less immediately and you should only need to bleed coolant for a 10 seconds. The thermostat often prevents the air bleeding through properly when cold (and closed).

Check it on the way, expelling any air (once clear coolant flows the air is gone). From now on any air you get in coming out is (probably) new air, so it'll be nice to know if you don't get any- and your head could be fine if so! Avoid opening the cap pressurised or letting too much coolant out each time you let the bubbles boil through the bleeder screw. Be careful not to scold yourself- the coolant can spray off the fan into your face if the engine is really hot. It takes a minute to pull over and check, better safe than sorry I say. I hope you don't take this the wrong way, we're just concerned for a fellow member. Warped heads are expensive and hard to fix. 'Nuff said now... good luck, Nick
