VR6 Lots of vibration/no power following oil change

[Son_of_Thor 0]

Hi folks,

 

Dropped the oil/filter at the wknd and also the coolant and then replaced like for like. Since then, there's been a lot of vibration below 3k and hardly any power at all - she isn't revving very freely either...

 

Anyone any ideas?

 

Cheers

I know this might sound like a silly question but have you made sure the oils not overfilled?

Hi,

 

Cheers for the reply - I've checked that and the oil level is fine....

What sort of oil did you put in .. ?

[Son_of_Thor 0]

Standard 10w40 semi-synthetic - same stuff she always has and I've never had any issues before. Some-one has mentioned to me that it could be be exhaust related?

Because you changed the oil? It's not even the same side of the engine as the exhaust, so that seems unlikely to me. More likely you knocked one of the engine's temperature sensors when you were down there, I'd say.

I'd say one of the sensor wires has come adrift as well. Also check your plugs/leads haven't had oil accidently spilled on them and causing a misfire.

Already checked the leads, but I'll have a look at the plugs tonight and have a look at the wiring in case there's owt obvious

 

Cheers guys!

I had similar problem recently - oiled up MAF.

Took out the sensor blasted it with meths, gently cleaned it up with a cotton bud.

Cleaned up the K&N with proper stuff and [lightly] re-oiled it again with proper stuff.

Now runs better than she ever did. :D
