WTF!!!!!

 

did a compression test on number 6 and it came back almost zero, added some oil, still zero must be a valve or the headgasket , im not getting any smoke at all, just waiting for my mechanic to call back...

 

Having a bit of a nightmare at the mo :(

 

Looks like its coming apart again. :(

You really should compression test the rest too mate, before it goes, so you know whats what. Does'nt take 5 mins to do the lot.

 

For accurate results you should have all 6 removed and throttle jammed open......although thats not going to magically give you an extra 150psi lol :(

Have you checked the com gauge is tight in the plug hole or the threads

not holding pressure

 

I was just going to suggest that, it is easy for a small piece of grit to stop the compression tester getting a proper seal, clean it grease and try again?

 

Also what was the procedure you used to complete the compression test?

dont you think your being a bit childish posting and causing a hate frenzy before you've even let the lad who re-built the motor have a look himself:( i hope its not serious and its a easy fix but for christ sake calm down till its been looked at or you might have a lot of egg to wipe off your face mate

wise words indeed!

What I cant understand is why you only took a reading from number 6 when you had gone to the trouble of removing the balance bar, all six coil packs, and six plugs + fuel fuse to get a reading from number six??? As Paul said its only another 10 minutes to screw the compression tester in to the other five cylinders

And did you have the throttle wide open.

Over the past six hours since you posted up everyone has asked/suggested you do all six and post up all the readings accurately but still you havent?????

Can you confirm you actually removed all six plugs to do the reading??

And was the gauge fully screwed in to the plug threads??

Yeah my compression tester now reads zero all the time cause its broke and has gone in the bin!

Jesus christ guys ive been at work all day gimme a chance.

Its not a hate thread, i still rate scott as a good mechanic im just upset that the car hasnt run right since i left and seemed as though he wanted rid of my car, When i bought my uprated clutch pivot ball last minute to be fitted he said to me i quote "im beyond caring anymore mate". i took it on the chin as i knew he was busy and my build had been put back a while already.

And i did actually test the cylinder next to number 6 which i think is 4??? it went all the way up the gauge, yes i will test the rest 2mow, i didnt have time today as ive been cooking for a party of 180 peeps so been stressed out all day and all i can think about is the damn car.

fuel pump fuse out, tester in cylinder nice and tight, turn over the engine foot on throttle.

 

rEMIND HIM YOU KNOW WHERE HE WORKS AND TRY AND SLIP IN HIS CLOSE FAMILY MEMBERS NAMES AND WHERE THEY LIVE TOO!!

 

No need for that mate.

I dont want to give scott a bad name he is a diamond geezer, I have not said anything against him have I?

Il still recommend him to people, which i have done, he knows the vg30dett and owns one himself, think hes planning a rebuild of his own, carrillo rods etc etc big bucks£££......

 

Didnt realise it would turn into a hate thread sorry.

As i said above i was in a rush and ive been at work, just got home now, i managed to sqeeze in a post earlier in the office, but just about, my manager is gay and was dieing for a poo and was being a real queen about it, rushing me etc!!!. not that that has anything to do with the topic but thought id enlighten the mood a bit, its hard to show what kinda emotions your feeling over the net but i was quite calm earlier today just a bit upset.

 

First thing 2mow im gunna test all cylinders just to be sure, last thing i want is egg on my face and :D

my manager is gay and was dieing for a poo and was being a real queen about it

 

:rofl::rofl::rofl:

were the lifters replaced during the rebuild ?

this because a bad/stuck lifter can also cause a valve to stay slightly open.

I dont think they were, he should of replaced those? i didask him about those but he said they were fine.

 

 

how are you getting it back to scott?

 

I dont know, dont want it driven there like that.

 

Was the engine warm and had you taken all of the plugs when you did the test?

 

Nope car was cold il do a warm test later today.

got to babysit for a few hours now.

I think now that you have to wait until the 27th, you've time to isolate the most common checks and problems mate, so you've a clearer idea when it goes back to scott. Am sure he's more than capable of opening up and engine, swapping a few parts and putting it back together, putting it back in the car though, can be a different story. I've seen so called specialist's get this important part wrong.

Theres a fair bit of plumbing and wiring to be done, right!

Your problems of erratic idle, lumpiness and stalling are classic for air leaks or incorrect fitted pipework. Am sure at the start of this you done the odd bypass or deleating of pipework hosing ???? if so this must be done correctly.

So back to the beginning, is Vijay still coming around to see you ? he's capable of doing a conzult check for errors and correctly doing a boost leak, get those areas cleared first, if vijay ain't coming round, do an ECU dignostics yourself.

Once the those 2 jobs are done, and Vijay is there, are there any hoses that appear to be incorrectly fitted, in their wrong place ( i've seen it happen a few times). Now move on to the next one, timing, check what it is.

Finally, i would take it to any local garage and ask them to do a compression check, yes it's gonna cost about 30-40 quid, but A) You'll have an expert do the job so you know it's right and B) You'll be armed with this info when you see Scott who would question your tests over that of another garage, this wil also tell if the garage are getting near zero on No.6, and that you ain't gonnna end up with egg on your face.

Myself and vjay are almost certain its a bad ecu, the conzult was not reading the ecu properly and it kept hanging. There was no reading to the left o2 sensor which i put a volt meter straight from the ecu pin.

Andy p has supplied me with a new ecu which i will fit saturday. Although there are a few bits and pieces still to look at as the car was idling fine before the build so its not all down to ecu.

 

Good idea il take it to a local garage for a compression test always good to have a second opinion. I will be over the moon if my tests turn out incorrect.

 

If it turns out to be a broken valve spring from z1 then im truely screwed. What are the chances of that?

 

Right im off to do a warm wet and dry comp test on all cylinders.

Its the moment youve all been waiting for........................................

 

 

D=dry

W=wet

 

D,140 V D,50

W,220 V W,60

 

D,150 V D,143

W,220 V W,190

 

D,139 V D,155

W,220 V W,200

 

 

Number 6 has still got oil in it from yesterday so not much of a dry test. but yesterday max was 20 psi looks better today.

 

oops think i may have overdone it with the oil a bit. got carried away :(

Jimmy, scots not out to screw ya mate. I think why he was not intrested anymore is because the job started out to be one thing and you continualy added to it. Because you kept adding My engine date got backed up, and up and up and teh car still isnt able to get in teh garage till next friday, a whole 6 weeks from when it was due. Now add this to at the last minute you adding something else, I think I would loose intrest.

 

I know for certain he isnt a cowboy, tehre are way too many people who have had engines built by him that are more than happy for him to do a duff job.

I know mate but all i added were the rods and they took one week to arrive, before that i added the injectors which were no where near being fitted so they wouldnt have made a difference i added the clucth pivot last minute but it arrived next day so didnt set back anything either. Another thing i did do was take a few bits home to paint which were far from being fitted so really it was just the rods so 6 weeks is a bit exagerated. He did mention his machine shop being behind schedule though.

 

Im not doubting scott at all im just upset, its either a faulty part or a fitting issue.

You were saying it was the ecu, then that could have run an injector lean and burnt out a cylinder, it may not be scotts liability at all and by airing your tinkerings on a public forum you have admitted intefering with the workings of the engine, and its warranty:(

It hasnt burnt out a cylinder i think id be getting a bit of blue smoke if it were the case. and the number 6 plug like the rest of them are coked up, lean i doubt!!! but i get where you going there topass

 

Right now im confused, it started missfiring on another cylinder so i removed the plug and cleaned it up.... erm now its running on all 6 again???? ok what does that mean? must be a funny valve somewhere? Or has the oil ive put down the bore increased comp temporarily?

spoooooky, i'm sure it'll be fine jim

  • Author

It wont be fine if the compression is still low. Is it common for an engines compression to change like that? Yesterday it was 0 psi dropped a bit og oil and it went up to 20psi and again today i did a dry test and it came back 50psi wet 60? all in the same conditions.
