Evo 9 with mivec Yes the blocked passages are supposed to be that way. Crank and cam triggers look correct for tdc positions. I see you are using a balance shaft elimintor. Is it a full length race shaft or is it just the stub shaft? And also the balance shaft bearings were flipped around to block the oil ports right?

Yes for stub and yes both holes are covered also 4 oil squirters are blocked off… I’m sending the ecu to link for an update and to check if there’s anything wrong with it… the car should of turned on. I even removed my alarm thinking it was being creating some block. But nothing. Once I get the ecu back we will see Quote Link to comment Share on other sites More sharing options...

I couldn’t be at peace knowing that it might happen again after spending all this money hmmm, kinda an odd reason to just eliminate them. they actually work very well for cooling the piston and lubricating the pin and cylinder walls. They arent expensive to replace. As far as them breaking, Iv seen this happen because they get installed crooked or not positioned correctly. Then depending on piston design and skirt length, the skirts can contact and break off the squirters, More likely in a stroked engine, but most times they can be carefully bent into a position that doesnt contact anything and they will live happy there. Iv built many performance 4g63s and never heard of anyone blocking off the oil squirters. But many ways to build an engine. My suggestion would be install them for peace of mind vs remove them for peace of mind. I dont have experience with how a 4g63 runs with them blocked off so that would be word of others but they are there for good reason.

I wouldn’t know much, the guy who did my block is very good so I trust his advise. We will see how it goes I think this is like a what’s the best clutch or what’s the best offset kinda thing lol correct me if I’m wrong this is my first build.

K4Tuning Posted October 25, 2023 Report Share Posted October 25, 2023 @Robsevo9 It could be, Like I mentioned there are many ways to build an engine, If it works without any issues then great! Just not off to a great start lol. So If everything checks out mechanically then you gotta start fishing electrical and tune related.. Ill keep thinking of why it woudnt start. Iv seen the mivec gears installed wrong on the cams and it will smash the alignment pin into one of the oil holes. Its hard to do but iv seen it. The timing marks will line up but the engine wont have compression. If you have good compression that is unlikely. Good evo 9 compression is around 160psii believe, can be more or less depending on piston specs. Quote Link to comment Share on other sites More sharing options...

Robsevo9 Posted October 26, 2023 Author Report Share Posted October 26, 2023 Question! How do I know if the sensor on the crank is working? I took the timing belt off because I removed the head should I change it? Quote Link to comment Share on other sites More sharing options...

I took the timing belt off because I removed the head should I change it? The crank sensor will be a 3 wire sensor. Check for Power and Ground on the power and ground wires. The third wire will be the signal wire and will change voltage while the engine is turned over. You should be able to turn the engine over by hand and see a change in voltage on the signal wire as the trigger passes the sensor. If no voltage is not present, or if voltage doesnt change at all then there is a sensor or wire issue. Cam sensors can be checked the same way. As far as replacement, If you are unsure of the sensor, it might be best to just get a new oem sensor. I think oem crank sensors are slightly more expensive but I only suggest oem sensors and spark plugs. ILFR7H is the factory 9 plug number.

Thanks, I’m putting the engine back together this weekend and will test for that. Does the ecu have to be connected? Or the key on? Quote Link to comment Share on other sites More sharing options...

Does the ecu have to be connected? Or the key on? I would plug the ecu in. I actually dont remember if power goes through the ecu before it gets to the sensor or not. Easy enough to find out, just key on the car without the ecu plugged in and see if you have power and ground at the sensor. If no power and ground then try with the ecu plugged in. You can use a stock ecu plugged in for testing if your link ecu is getting checked. Quote Link to comment Share on other sites More sharing options...

Can you imagine it’s the ecu that’s acting up? I sure do hope so I been chasing this issue for days Quote Link to comment Share on other sites More sharing options...

On 10/24/2023 at 11:06 AM, Adamw said: I dont see anything obvious in the log, it appears to have everything it should need. As already mentioned the log shows the ecu has all signals needed to run the engine and it shows fuel and spark being commanded. All important sensors are working and giving realistic values. 4 hours ago, Robsevo9 said: Can you imagine it’s the ecu that’s acting up? It is very very unlikely to receive a DOA ECU, they are all tested for 24hrs at extreme high and low temperatures with all IO monitored before shipping. Especially when everything is working in the log and you have already physically confirmed you have fuel and spark, there is not even a hint that there could be an ecu issue.

Thanks Adam, I’m just lost! Yes I tested the spark on 1-3 and it had….

Robsevo9 Posted November 18, 2023 Author Report Share Posted November 18, 2023 so i got the ecu back and still it wont start.... i have spark at all 4 plugs but car doest want to start. new starter also. this is the new log test 2.llgx Quote Link to comment Share on other sites More sharing options...

There's several ways cylinders can leak. head gasket.. piston/rings mis-sized/gapped.. valves not properly lapped or out of lash spec, cracked walls... Also you sort of need a leakdown tester and/or permanent airsource (electric bike pump? probably too noisy) if you want to identify where the air is going - you can then listen at the exhaust, intake, coolant pressure cap, oil filler cap.. Best to ask the engine builder. I hope it's something simple. Quote Link to comment Share on other sites More sharing options...
