Lots of blowby - Have some questions Options

Compression::::Leakdown

1::::195:::::::::::::4% Exhaust Valve
2::::195:::::::::::::16% "
3::::190:::::::::::::4% "
4::::200:::::::::::::9% "

Test run by Intense Motorsports in Gilbert.

I'm getting lots of blowby venting out when coming to a stop. Sometimes a little, sometimes a lot.

Should 16% on cylinder 2 cause that much trouble? If not, what else would cause this?

Am I hurting the turbo in any way from this?

Does installing a catch can take care of all excessive blowby issues?

temporary solution is to put a catch can in and see exactly how much blow by is accumulating.

i have no idea about 5sfe motors but the 3sgte motor tends to have a good ammount of blowby, figure out about how quickly it is accumulating and go from there. it wont solve any problems, but it will help to troubleshoot what your problem is and how big it is, if there is a problem at all.
