very nice work sierra.
well i am pretty convinced that the EGR process is ahead of the engine and oil technology......
The article indicates that engine manufacturers are some way off solving this issue and proposals could include higher wearing metals, bypass filtering etc.
One absolute that i have taken from this is to complete 3 oil changes per 15,000 (i.e. every 5k) or at least every 7.5k which is what i would normally do.
However, wikipedia had this last few lines,
'In most modern engines, disabling the EGR system will cause the computer to display a check engine light. In almost all cases, a disabled EGR system will cause the car to fail an emissions test, and may cause the EGR passages in the cylinder head and intake manifold to become blocked with carbon deposits, necessitating extensive engine disassembly for cleaning.'
i guess a scanguage can be purchased to determine the check engine light type. nothing worse than thinking you have a blocked EGR light but it is for something worse! Does anyone know enough about the internals of the head etc to know if the blocking of the EGR is a long term problem to this part of the motor. it seems that in any case you clag up the inlet port which seems ridiculous or upstream of the egr pipe if you block it.
Maybe Monster is onto something by venting it as the gases vent to atmosphere (they would via the exhaust otherwise) and it probably doesn't effect the 'check engine light' as there is still flow. i think in any case i might get an EGT sensor fitted (do scanguages monitor exhaust gas temps if you have a sensor?) to make sure it is all kept in parameters.
can anyone enlighten me more on this 'catch can' setup?
man this thread is a bit heavy but hopefully we can find a good result.
This car is like a bad drug habit. It is taking all my money and time, my family are concerned, but new mods just feel sooooooo good.
