I have a 2002 R50 automatic and I was wondering how to properly seafoam the engine. I have seen many different variants so I am a bit confused. Any one have or know of a good set of instructions. TIA!!!!!!!!!!!!!!!!!!!!

 

I did mine through the pcv valve on top of the engine. It just sucks it in for you.
I have also heard that the vacuum line for the brake booster works, but I wouldn't risk cracking that plastic line, it costs $60 to replace.

Alternatively you can buy the seafoam can with the bendy straw and
Spray it in the intake after the filter ( I think).

Here is the pcv valve line.


The yellow arrows point to it, same on r50.


Take this line off and pour the seafoam in there slowly, let it suck it up and when the rpms start to dip stop pouring then repeat without letting the engine stall.

 

Thank you that is what I was looking for. Do you use the whole can or only part of it? Also you're pouring into the hose part correct?

 

I used 1/3, I'm not sure if there is a proper amount but I did 1/3 in the oil, gas, and engine. And yes the hose should have a suction with the engine running.

 

sounds good that is what I will do Thank you
