I have an 83 blazer 6.2 banks kit and so on it seems to make a lot of blow by at idle. The truck starts good. Doesn't seem to have low compression. Is this a 6.2 thing or do I have a possible problem. Thanks in advance.
Some blow by is normal for 6.2/6.5's (a little smoke from the oil dip stick tube) and have you cleaned the CDR valve lately? a clogged CDR valve will cause excessive blow by.
