Hoppi's Del Sol SiR going H2B (UPDATE 2016)

hoppi05 · Post by **hoppi05** » Thu May 21, 2015 10:45 pm

Ok so we got the engine running again tonight see the YouTube video below as you will here once we revved the engine it started to hunt which we thought was an air lock and it is however we also saw bubbles and hissing from the thermostat housing so on inspection the new thermostat and new seal was not a good fit luckily I have a new Honda thermostat seal in my box of bits so that will be fitted tmoz and the cooling system refilled. There may also be another water leak however it was too hard to tell with the leak from the thermostat housing. I will be placing a nice bit of sealer on the new seal also just to make sure

Well some good progress yesterday and today

the car is back on all 4 wheels finally....

So the hunting wasn't an air lock I will try and explain the root cause. So as soon as the car got warm it started to hunt from 500rpm to 2.5k rpm just a steady bounce. We bled and bled the system to no avail so we looked elsewhere as we had last week. So there was no vac leak which we could easily test by covering the inlet throttle body and the engine cut out, basic but it tells us a definitive answer. So we were really starting to struggle when we disconnected the IACV sensor the hunting then stopped we got a cel but no hunting as a side effect the car sounded rough not bad but not as a clean tick over as you would expect. We then reconnected the sensor and the hunting returned? We powered off the car disconnected the battery to reset the ecu. Once reconnected we restarted the car this time we removed the temp sensor that connects to the end of the inlet chamber on the righthand side if you are looking straight on from the front of the car. This had the same result a cel a rough idle but no hunting?? We did the disconnect and reconnect of the battery and tried the same again with both sensors on and off in different orders and together with the same results, once put back to normal the hunting retuned.... So we somehow deduced it had to be the IACV as this is the only electronically controlled part of the throttle body workings. We removed it and other than being a tad mucky it all looked ok. Whilst rummaging through the spares box we found another h22 IACV so we fitted that as it looked in good order and low and behold car ran without an issue!??!?!

So not entirely sure what was wrong with the original IACV but something was a miss?

To note we have done a vacuum loop/delete and the coolant bypass.

Either way the car run perfect other than the timing and idling which needs tuning correctly by a pro not us

.

So after that we run the car got it to temp and decided to drop it and test the gearbox as shown below:

After the test we have found another coolant leak but this should hopefully be a much easier fix.

We also fitted 15mm hub centric hubs to the front which required the original studs to be shortened to 2cm each but made the fronts fit perfect. hopefully tomorrow I can check the rears to see whether to order 15 or 20mm hub centric spacers?... I will use the old basic spaces to judge which to get.

So still a lot to do but the gearbox and clutch work so thank you to the seller's I got them from for there honesty, tbh the clutch felt and bit like new

To do

Shorten the air intake pipe as the filter is hanging lower than the engine

Fix water leak

Secure all loose hanging harness bits

Rewire the hids

Refit the bonnet hopefully it shuts lol

Take it for some test runs

Get the timing tuned by a pro

There is a lot more to do also but i am not listing everything

Good news mate, this is what happened to mine and sure it still does, i blanked the iacv of with morfs plate he done me, i had it disabled on the ecu but i still had to have it plugged into the sensor.
Then bought the rosko kit but still didnt help, needed setting up properly but didnt have time to which i regret

well it is finally fixed

the hesitation faults were the knock sensor and the fact we must have forgotten to tighten it up

so a lesson learnt the hardway and the fact our checking wasn't as good as we thought or should have been!

anyway now up and onwards i can get back on track and finish the other parts off whooo!
