well it time for a rebuild. my ve30de decided to turn off on me in my neighbor. new fuel pump works, 370cc injector works, disconnected MAF still no start. change cps sensor, check 1 coil it has spark which means that transitor works. change tps, new spark plugs, new coolant sensor and still crank but no start.

so i decide to do what i tried to ignore, a compression test.

cyclinders 1,3,5 = 175,170,175

cyclinders 2,4,6= 60,80,60

how does one side of the engine can go that low compression?
i did do the compression test with throttle closed when i know you supposed to do it with throttle wide open. but i dont think that makes a huge difference but im planning tomorrow to check it again with throttle wide open. ill keep u guys up to date.


p.s i only drive the car 5 miles a day.

 

Bent valves or blown head gasket most likely. Im not experienced with VE but if it was me I would recheck and pull the head.

 

i also forgot to mention i did a wet compression test and it raised the compression to those numbers

 

Maybe a shot in the dark but have you checked your fuel pump fuse and fuel pressure?

 

I retested the compression on the low cyclinder and compression is above 125 psi. What i believe happen was the 370cc injectors wash out the cyclinder and flooded the cyclinders. It ran for about 25 miles without a problem but now it wont start. When i checked injectors i did hear the injector spray open for about 5 seconds long which i think is a long time.

 

Did you have a tune done after upgrading injectors and going turbo? Just a suggestion but if you think the engine may be flooded did you check to see if the plugs are wet and try getting out some of the excess fuel and dry the plugs up?

 

plugs were wet, I let the car sit for a week before I try to crank car again but no luck. I'm going to swap the stock injectors back on to see if it works. I have spark so crankshaft sensor works. I can hear injectors clicking but I think I have either leaking injectors or some relay or fuse etc.. malfunction.


good news is the I have good compression. I install 370cc injectors and was schedule for a dyno tune the next day. But I had to cancel because my power steering pump completely crap out on me. after replacing the power steering pump I drove for about 8 miles and the car turn off at a red light. it started back up then I drove home. restarted the car and drove 2 miles and car loss power then finally shut down and never restarted. there is my story. it has to be something stupid I bet.

 

Sounds like your definately flooding the engine. It could just aswell be a leaky injector not seated properly in the rail or pinced o ring but with those 370cc injectors your probably dumping in way to much fuel without being tuned for it to begin with. Have you tried pulling the fuel pump fuse and cranking it a few times to help get rid of the excess fuel thats in the cylinders? Even though it sat for a week sounds like the fuel still hasnt evaporated. I think your right by swapping your injectors back to stock until your ready to get it tuned for larger injectors. Are the injectors you put in running on the stock ecu?

 

Yep i try the deflooding method and still nothing. I'm stock ecu, i do have nistune but no license yet on spare ecu. Before swapping injectors I'm going to test for leaking injectors with fuel pressure guage. I'll even check for the oem regulator.

 

you have the stock tune on the motor...so everytime it runs it will pour more fuel into the engine than it's ever needed. the latency and flow are set for a much smaller injector...now that you have 370CC it will literally dump fuel. what is you AF reading?

IMO your compression issue is worn rings. when the injectors prime it usually primes all 6 cylinders..not just the back. if it was too much fuel washing the cylinders it should appear on all 6 banks that it's low on compression not just half. if compression goes up after adding oil then it's clear the rings are worn. is that how you determine that you have good compression...after adding oil?

how often were you changing the oil after the turbo swap? you might have fuel dilution and the oil probably broke down.

not a VE expert but just a thought.

 

Compression went higher with a wet compression test. But after a week later with a full charge battery and throttle wide open my compression double above 125psi. Injectors is definitely the issue. Im due for a oil change. It's been 3 months since last oil change. I think I'm going back 10-40 oil. And maybe a can of restore engine treatment, i heard it improves engine proformance n compression.

I do have a safc not installed. I was thinking about installing that n lower the injectors setting. But for some reason pinout 38 on ecu doesn't exist. Pinout 38 is supposed to be the throttle position sensor. It's blank, empty.

 

ahhh ok..gotcha.

i guess right now you just need to fix the fuel problem.

 

Research research research. NA engine. Onwer wants to boost. Plan plan study study. Do it right the first time and not ruin an engine. Not here to hate. Just stating that error without a tune causes more problems that anyone needs..
Good luck Tony.

 

That was my plan. I installed 370cc n next day was going to get tune but power steering pump went bad. On my way to get pump replace, on the drive home is when car shut off.

 

you check to make sure the plugs are not fouled up??

 

Plugs are good i really believe it a bad cps. Cuz when cranking the engine the rpm needle doesnt even move at all.

 

ecu issue. if you dont have a check engine light when key is ON position then you might have a bad ecu or no power going to ecu. check for voltage to ecu.

 

Had a gut feeling it may have been an ecu issue when you mentioned one bank of cylinders were o.k and the other not. Might be a good idea to stick with the stock injectors atleast until your ready for a proper tune. Glad you found the issue Tony.

 

Thanks . Thinks are easy to figure out if u have the right tools. Logic probe and continuity tester are good investment for electric issues

 

Engine started but died within 30 seconds the engine is flooded extremely bad I had to leaking injectors planning to buy new spark plugs. crank it couple times with the fuel pump fuse off and see if it starts and hold the idle. it turned on so I'm happy about that engine is in good shape obviously the front three cylinders have low compression because it was washed out by too much gas.

 

the verdict is in ladies and gentleman.

Guilty for TIMING CHAIN

definitely out of timing, i unbolted the cps and turn it pass where the bolts screw on, the car started and stay on with no problem. it ran like crap and you can hear the chain rattling inside the cover. time to pull the engine out smh

 

All guides and tensioner pads look like this one. Front cyclinder head had broken plastic piece from tensioner and guides. This is the reason why it was off timing. To much slack

 

Do you have any pictures of the actual broken tensioner(s)? These guides, while worn, wouldn't make the timing chain jump or anything of the sort. The VE that I rebuilt last year, all the guides looked like your picture - pitted/damaged plastic, but it never jumped timing. Curious to see the actual culprit(s) on your engine.

 

I'll post them later today. But remember the valves hit piston that alone tell you that the timing was off. Which cause the no start issue. Some of the tensioner plastic broke off as well.

Bent valves was the cause of low compression in cyclinder 2,4,6.
But even then compression was over 130psi on those cyclinder, engine should of started.

 

 

 

I guess you should have titled it as "Ugly Ve30de timing chain job from hell".
(Since the last 3 characters in your video URL are "feo", ugly in Spanish.)

 

Lol
