So I rebuilt the head on my GSR & have everything back on and hooked-up. I try to start it & it won't fire up. While I'm cranking it over, I get some oily smoke coming out of the throttle body, and my plugs have a black oily residue on them when I pulled them. Anybody have any ideas on what's going on?
Also, while I was cranking there seemed to be a bit of hesitation/resistance to the engine where it would bog down the elec. system for a sec. It might've been due to the battery losing charge, I've got it back on the charger right now.

Any suggestions are welcome. Head is poerted & polished with supertech valves, omni dual valve springs & Ti retainers, CTR cams, skunk2 cam gears, power enterprise timing belt, skunk2 intake mani. Cams & crank are aligned correctly, wires all go to the correct cylinders of the distributer & I've checked all my vacuum/coolant lines.

Open for any ideas, one last thing to mention is that the gas in the car is ~1 year old. I had about 2/3 a tank & added 5 gal. of brand new gas. Could I need to drain my tank & have all fresh gas in? Again, let me know what everyone thinks.

Thanks

 

Did you check if u have the plug wires in the right order on the dizzy? Also change or clean the spark plugs. Make sure the plugs for all the sensors are connected to the right ones

 

Yeah, I actually just got back from the garage to make sure All wires going to the correct cylinders & I've cleaned off the plugs. Battery is recharging & I'll give it another go.

Anybody else have any thoughts on what could be going on?

Also, I noticed that the throttle body puffs a little air outward while cranking. Is this normal? I've never started the car without the intake piping on. It's coming from the 1/2" orifice inside the throttle body before the throttle plate.

 

very small possibility, but sounds exactly like what happened to my friend. He was high when he put his head on his block. I was looking at it and saw the tab for his headgasket was not there. It was upside down and backwards. It sounded like it was puffing air through the intake manifold. Its worth a shot of advice.

Man, I almost did that when putting on my head (put on the head gasket upside down.) I'm glad that I had someone with me to give me a sanity check and point out that some orifices were covered by the headgasket and it was not right.

That would really be bad if that's what happened.

Also, I thought that leaving gas in your tank for that long is bad.. Doesn't it become all pasty ? At least that's what I saw on TV where the repair guy was showing how to fix a small weedwacker motor. There was fuel left in the motor for too long and it got old and gummed up everything.

 

I'll have to check the headgasket, I really hope that's not it. My dad's going to drain my tank this week and when I go there this weekend I'll put new gas in it. I really hope it's not the headgasket, not that gummed up fuel would be much better.

What would one do if the fuel has gummed everything up?

 

Don't quote me on the gummed up fuel. I have little to no experience with that. Just what I saw on TV with the small yard tool motor.
But what the old fuel did was clog a fuel filter and harden some rubber gaskets and make the choke stick.

 

I did add ~4 gal. of fresh 93, unfortunately there was already 2/3 a tank in there.

I don't think I would install the head gasket upside down, but it was a mugen HG and didn't have the 'UP' on it. Does anyone have a picture of where the head gasket tab sticks out from the block so I can verify next time I'm working on it?

I'd really appreciate it, thanks.

 

Also, does anyone have any info on why smoke would be coming out of the throttle body hole? is that normal, where does that hole inside the throttle body before the throttle plate do?


One final thought, I read a post a while ago from someone who had the same problem and someone commented that he washed out his rings. They suggested blowing compressed air in each cylinder, adding 1/2 cap of oil to each cylinder & replacing plugs. Does this sound right?

 

The hole on your throttlebody is the port from which the IACV works.

You can wash your rings if you continue to crank the motor without any ignition occuring. It is also possible to wash your rings if you idle the motor with large injectors running at a low duty cycle, the fuel will not burn completely, if you are monitoring AFR's, you would see them below 10:1

Don't crank the motor with the injectors fireing for more than 5 seconds at a time, and wait a couple minutes between attempts for the fuel to evaporate.

Make sure you are getting spark.

Sounds like you are getting fuel, but if you get an injector diode tester, that is an easy check.

If your motor is assembled correctly, and you have spark and fuel, you should have a running engine.

Also double check your ECU, engine harness, and engine grounds (front and tranny).

 

so is it normal to have air coming puffing out of the IACV while cranking? Or does that indicate something is wrong?

Thanks for the suggestions 92TypeR, I will make sure I'm getting spark.

I don't have my wideband hooked up yet because I wanted to get the car running before I start splicing wires, but I'm still running stock injectors until I finish my ITB setup. My ECU, harnesses, and grounds are the same as before, so they should be fine. I didn't want to swap my chipped ECU in until I knew the car was running properly.

I'm guessing it's either the bad gas or it's not firing for some reason.

Thanks again.

 

Still wondering if it is normal for air/fuel to puff out of the IACV hole on the throttle body?

Oh, and one last thing, when I was recharging the battery, I noticed that the evap purge solenoid was VERY HOT to the touch (so hot I could barely touch it), so I unplugged it. why would this be? Is it normally grounded through the manifold & now that I have a skunk2 mani & hondata insulator it needs to be grounded? I have it mounted off the iacv via a bracket, but maybe I should mount it off the firewall?

Thanks for all the input.

 

I was gonna first say wrong firing order....

The gummy gas more than likely isnt the case, seeing that the weed wacker probably had an oil mix.

yea thats kinda what im thinking because even with a headgasket installed wrong, you still would fire if he had spark, even if it only ran for a second.

To be honest man, check your grounds, firing order on dizzy should be

3 4
1 2

and be sure the wires are pushed down tight on the spark plugs and on the dizzy.

If its not firing I would say you have an ignition problem..however I am not sure why your have smoke out of your TB...it it probably oil in your cylinders trying to burn and coming up through open valves into your head and out the manifold...

which if its oil then i would say your headgasket is wrong. Also, you don't have a vaccum line going to your pcv do you?
