Is this bad?

Had a decat fitted about 4 weeks back...

Dunno if the smoke is a bad sign!

Cheers

Colour is it? From the video it looks like it has a blue tinge to it...Which indicates oil.

 

[Andyk1801]

I've checked the oil and it's not
Losing it on a regular basis, it's not loosing coolant No gunk on dip stick or in oil cap..

a lad at work told Me it was white when he was behind me the other day on the way home...

 

[Tony172]

I'd say it was burning oil personally

 

[Christopher]

It definitely looks blue. Hmm.

 

[Andyk1801]

What would be causing it to burn oil? Is that a bad thing? I know it's not good but on a scale of 1-10 one being good what would you say?

 

[RoryW]

11

 

[JackJack]

Valve seals are a possible cause iirc.

Scale of 1-10 depends on how bad it is but i would get it sorted.

Amazing, il leave it then! Lol

Basic estimate for repair? Anyone know?

Would depend on the cause. Where are you I'd take it to you nearest specialist.

 

[Andyk1801]

Lancaster... There is a Renault dealer near me but I'm guessing they will be costly!

 

[JackJack]

Don't take it to Renault whatever you do.

 

[Andyk1801]

Any specialist close by to me?

Stem seals is usually first thing on a morning if they are pretty bad (common in old ford cvh's) and on the overrun as the oil gets pulled past old weak seals. Rings tend to be under load.

Blue smoke is oil.

Black smoke can be fuel. Much more common on older cars especially ones running carbs.

White smoke is most of the time just steam from moisture in the exhaust system and should clear fairly quickly. White smoke can also be the early signs of a head gasket depending on how it's going to fail. Had an XR2 blow a bit of white smoke on the way home after a sprint once but it was fine while i was driving it around. The head gasket went at the next event. It turned out it had been fitted over lumps of the old gasket. God knows how it lasted as long as it did.

Either do a compression test yourself there are plenty of guides around and gauges are fairly cheap or take it to a garage or specialist and get them to do it and a leakdown test as well. That should give you a reasonable picture of whats going on and an idea of how much it's going to cost.

It's a minor arse to get at the plugs but easy enough.

Nothing wrong with my local renault garage but you need deep pockets if you go to a dealer.

I'd say ring seal/blow-by is the most likely cause of that not stem seals.

Compression test and a leak down test would be the next step. Is it high mileage this car or has it just been punished?

[Andyk1801]

Just hit 90k. I have owned it for 6k got almost full service history. Well looked after.

 

[172Ben]

Rings.

As mick said do a comp test

 

[Russ_16v]

i would also say rings, looks like it tends to smoke once it's under load.

Take it to someone like Mick - it's worth the journey to make sure the jobs done right!

 

[Andyk1801]

Where is mick based? Cheers for the advice people!

 

[JackJack]

Nottingham mate. Unfortunately there isn't any specialists that close to you but as said it really is worth the journey to get it done properly.

 

[Andyk1801]

Cheers pal I will look into it soon , thanks buddy.
