Cool Runnings by MrB

Couple of weeks ago I had a new thermostat fitted and then I fitted my new PCV (Positive Crankcase Ventilation Valve) housing and filter and connected my Synergy 2.

Since then it has been quite noisey when started. More clattery than it was before.

Today after sorting the tank seal I started it and again quite clattery on startup - sounded like my old Cavalier TD.

So I ran it til hot and then gave it a standing Italian Tuneup and then it was running as before - all lovely smooth and quiet. There was a short, 5 or 6 second period, during the high rev run where it did run lumpy and blow a little blue smoke, but then all smooth and back to how I remember it.

Does anyone have any ideas?

Obviously I'll have to wait a while before I can start it from cold again, but was just wondering.

I would add I have not connected the MAFAM section, just the TU3. Even though it is a bit gutless at low revs and actually needs quite a few revs to get it going from a standstill. But it never produces any smoke, so I don't think it is overfuelling, although to me it always smells a little chokey. However both Russ and Andy Willi disagreed with regarding the fumes smell.

The synergy will make it a little more "crackley" especially from cold as it increases the fuel pressure & therefore the amount delivered.................nowt to worry about ;)

Makes me feel better.

I will get it over to Russ at some point for him to put his box of tricks back on it and have another look around.

Be good to know whether the MAF (Mass Air Flow Sensor) is good etc.

Alnwick is certainly very bonny. :D

Just a little more info on my cold running problem.

It was rattly again on startup the other day, dropped the clutch and much better, so I think maybe it just depends how everything is aligned when cold as to whether it puts a little extra strain into the engine.

However when cold it did seem to miss, every now and then, accompanied by a little blue smoke when it did. Would like to point out, once up to temperature this doesn't happen.

My thinking is maybe a sticky valve that is more prominent when the oil isn't up to temperature??

Anyone have any other ideas?

Might throw an engine flush in the oil and give it an oil and filter change, see if that improves things.

I also posted this problem on the OC site and one of the members over there told me how he had this same problem on his and that it was down to the oil having been slightly overfilled.

Now I have to hold my hands up on this one, as I topped up the oil only a couple of weeks ago, as I thought it was reading low and may have been the cause of my noisier engine.

Having had a further look around I found info over there on how to correctly check the oil level.

Seems you can't just dip the dipstick and take a reading but that it takes time for the bottom of the tube to fill after you have removed the dipstick for the first time.

Anyway I then had to decide how to get some oil out as I didn't have anything big enough to hold 6+ litres of oil. The method I chose was time consuming and messy, dipstick and copious amounts of Plenty Kitchen Towel.

Now runs like a dream again, with no missing and no blue smoke.

So if anyone else gets the symptoms of the engine missing, accompanied by puffs of blue smoke and can rule out the PCV, EGR (Exhaust Gas Recirculation Valve) etc, then it may just be that your engine is very slightly overfull.

It is now my daily driver :D

Was gonna drop you a PM, the Civic has gone so I now have the money to pay you for the wheels.

Unfortunately, my lumpy running and blue smokiness returned with a vengeance this morning.

Gonna have to take another look at this. Don't understand why it is only when its cold, as soon as it's up to temp no smoke and runs like a dream.

I was hoping to come see you to help me check I have the synergy set up properly as well. I don't feel the performance improvements others mention.

Jon & Russ

Is there any evening this week you are free so as I can come and collect and pay for the wheels from you John?

Also so as I can see Russ to complete the T4 session.

Unless you're both going to the Community Picnic on Sunday and we can sort it then?

Whatever is easier for you.

Am quite happy to sort at the community picnic on Sunday but equally as happy to call in one evening and collect.
