Hey guys,

Well recently I posted some info about my turbos dying, followed by the engine. Engine was opened up recently, and I took some pics on my Mob, exhaust valves are smashed, hence the 0 compression. Judging from the damage, the mechanic reckons its just the head that is gone, and the bottom MAY or MAY NOT be functional. He's getting the head reconditioned and may choose to "gamble" and put the head back onto the same bottom......for some reason that doesn't sound entirely correct to me. Anyways, this is for the tech gurus on SAU, judging from the pics, is it likely that the bottom end is gone? Or should the head just be replaced on its own. Prior to engine failure there was NO TAPPING bottom end sound, engine just seized, and refused to start.

Thanx in advance,

Ali.

PICS:

If that happened to me, I would also tear down the whole engine and rebuild it. The main thing is that nothing else could fail if it is rebuilt properly and new parts installed. I'd go a fresh eng any day, I'd have to save up first though.

Don't 'see how it goes' make a point of it that the whole motor needs to be rebuilt :D

haha that's what i meant, see how it goes with the mechanic.

I assumed from the start that I might need a full rebuild, but mechanic is a mate and is honeslty trying to save money........as much as I appreciate it, i think i'd rather not risk it.

he is not being a mate by allowing the engine to be put back together without a full rebuild....it will cost you more in the long run.

Absolutely DO NOT go with the "she'll be right" attitude

The heads off, get that bottom end out and have it rebuilt otherwise you are wasting your time and wasting your money.

Dont half do it

Pulling the head off with the engine in the car must have been fun...

at the very least get someone to do an analysis on your oil, they will be able to tell you if there are metal particles like bearings or exhaust valve parts floating around your engine.

this is a topic close to my heart atm :)

rebuild it no question

plus i find it easier now to drop the subframe engine gearbox the lot to do any work on the engine but it requires a two post hoist (but god does it make life easier)Once out its so easy to remove/work on everything

It will be worth it.

What components are you going to use in the rebuild?

Hmmm was thinking standard, but now that the budget has already been blown, might as well blow it further.

The car already has n1 nismo turbos, steel wheeled, but not ball bearing.

Car also has aftermarket exhaust and air filters, but thats it.

Might upgrade the internals, see what the mechanic says tommorow, any suggestions?

      RB25DE NEO with Haltech ECU

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.

      Could be correct. Meter might be that far out. Compare against a known 5 ohm 1% resistor.

      @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap.  (edit: I went out and did it right now, the line I had chosen did appear to have no vacuum on it, it used to go to the front of the intake, I've now completely blocked that one off at the bracket that holds several vacuum lines by the firewall.  I T'd into the vacuum line that goes from that bracket to the vacuum pump at the front of the car, but no change in the MAP readings).  Using the new vacuum line that has obvious vacuum on the hose, im still only getting readings between -6.0 and -5.2.  I'm wondering why the ECU was detecting -5.3 when nothing was connected to the MAP nipple and ECU MAP selected as the source. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.

      Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
