Primera is giving me trouble.

[Jinata]

I replaced the head (New set of cam shafts etc etc). I did all the timing as required (I think). The car starts but it doesn't idle itself unless I give it full throttle in which the car will only rev maximum to 3K Revs.

Any ideas?

Video of it below

[superls]

sounds like timing to me, or ignition.

 

[Jinata]

Hmm.. any advice or what to check? (SR20DE btw).

Also, whenever I stick in the key, without turning it. I get that beeping noise you would get if you left your head lights on when you open the door.

Have you tried asking over on NPOC?

3k rev limiter is probably the ECU going into "limp mode". Something ain't right.

I'd consider checking the ECU for errors:

The thing is it sometimes goes past 3K revs, it hit 7K when I revved it hard when my friend was adjusting the distributor. I just uploaded a video, I'll post the link once it is finished processing.

Spot on olly. Does the ECU light remain on when the engine is running?

Naw, It goes off when the engine is started.

Well then the cams are probably a tooth out. Do a compression test.

 

[Stani1029]

my k11 done the rev to only 3k and i changed the throttle body and that was the problem fixed, it could be one of the sensors on the tb???

I doubt that.....the MAF isn't on the Throttle Body on the SR20 and the MAF is usually the problem when it comes to engine revving/idling problems.

Well then the cams are probably a tooth out. Do a compression test.

Will the ECU know that the timing is out and cause an error code?

I'd start with check the Error codes, it's an easy place to start.

 

[Jinata]

Any ideas based on the video? - or were your responses to the video? :S:S:S

 

[Ed]

Yep that video looks like cam timing as it sounds lumpy and uneven DO A COMPRESSION TEST!

 

[ollie240585]

Only just watched the video.

After watching it and seeing this

I did all the timing as required (I think).

And also I'm not a fool to disagree with ed, timings out by the looks of things.

 

[Jinata]

Hmm, how do I do a compression test? LOL

With a compression test tool.

Remove the spark plug, fit the compression tester, crank the engine a few times. Read the compression tester.

Complete a test on each cylinder. I'm not sure what compression that should be though but should all be a similar figure.

WHEN DOING A COMPRESSION TEST BE WARY OF ANY HT LEADS OR DISTRIBUTOR AS IT WILL STILL SPARK

[Jinata]

Hmmm. You wouldn't know by any chance how much pression Ill be looking for in each cylinder?

 

[Ed]

approx 12 bar give or take.

 

[Jinata]

Cool, thanks guy. I'll love you all forever, and I'l let you know what the results are tomorrow.

 

[kristian]

Definatly a tooth or two out

loosen the dizzy.

start it.. and twist the dizzy completly oneway and the other see if you can get it to idle..

..also dont run the engine without cam cover bolted on.. a one in each corner at least bud..

on cg,s the exhaust valve is closed at about 20deg atdc, and the inlet opens about 20deg btdc, and if you,re 1 tooth out it,s nowhere near 20deg.
i would think sr,s are pretty similar

 

[Jinata]

Did a compression test.

Cylinder 1 - 12 Bar.
Cylinder 2 - 13 Bar.
Cylinder 3 - 14 Bar.
Cylinder 4 - 12 Bar.

Any diagnosis?

jinata

looking good (Y) , have you tried my suggestion ?

 

[Jinata]

Ive given your suggestion a lot of thought, and I'm wondering how do I know link from link as to where the cam shaft sprockets fit into.

It does have the 2 coloured links on the chain but they are never there when I set the crankshaft at Top Dead Center.

Any ideas?

 

[frank]

jinata

all i can advise (never worked on an sr is if the in/ex is,nt biting a thin feeler at about 20deg btdc/atdc (1 notch on a cg pulley=5deg) then you may be 1 or more teeth out
