The other morning I blew the head gasket on the way to work.

A mate and my brother and I have removed everything including the head, and that's where we finished last night.

I have ordered a new head gasket, intake manifold gasket, exhaust manifold gasket and a new gasket for between the intake manifold and the plenum.

Question is, what do I do now? Number 6 cylinder is full of coolant, its all mucky where the gasket used to be.

I've never ever done this before and neither have my mates, so any help would be HUGELY appreciated!!!

jeez that brings back memories :cool:

if you havent already get the coolant out and let the cylinders dry, without taking it to an engine specialist i dont know if theres any way to tell whether or not the bores have been affected. just empty the coolant out and hope for the best i guess!

The bores will be fine. Blow the coolant out with air or soak it up with a rag. Find a scraper to scrape the remainder of the head gasket off the deck. Dont lean the scraper to one side leaving deep scratches. Then use a honing stone (the large rectangle one you use for knifes) rub the deck of the eng evenly using petrol to assist. Make sure you use the fine side as they are generally course one side and fine the other. When the deck is apsolutley spotless and you can wipe it with a white rag and it doesnt change colour from dirt then the head is ready to fit.

Be sure also once back together to run thin oil for first start up, till it gets warm, drain it, new oil, run it again, tune it, drain it, then put new oil, do 500km, drain it again, then your good stuff.

Also do engine flush as well.

Will take a few hundred k'ms for all water to disappear, also, as it gets into small galleries etc etc.

Just watch for no color turning from black to cream!.

Cheers guys for the help

I just got another stock Nissan head gasket

Was gonna put it all back together on Saturday after draining the sump and coolant, cleaning the block to a mirror finish :D

But then found that there were two studs that had snapped off in head for the exhaust manifold. so i've gotta get them removed. Also the place that tested and cleaned my head pulled the cams etc out so I have no idea how to replace them! A mate said he'd do that tomorrow for me :)

Hopefully get the car running again soon!

Put new bolts everywhere, will cost a measly $30 or $40 bucks but will save you damaging your engine again,. Get new head bolts, manifold bolts, exhaust housing bolts etc etc.

Go get em now!

      Duncan's V37.......race car?

      By Duncan · Posted

      Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.

      So 10/10 times that code is coil packs? I mean if that's the case ill drop the $400USD or so to replace them. I didn't know these cars threw codes before the issue became an issue.
