Hey guys, I have 2 fluids now leaking out of my 89 CRX Si. Both oil and antifreeze. It doesnt hit the ground so my first thought was headgasket. But everything I check leads me to believe against that. A compression tested showed higher than average compression in all pistons, and there is no visible water in the oil and vice versa. There is also no calcium buildup around the plugs and the cap. Where else could i be getting leaks? Does it sound like the same leak or two different ones? I am definetely burning oil as on acceleration I get a big puff of blue smoke. Any help would be appreciated, thanx in advance.

 

a compression test just tells you the max comp you get in the cylinders

you need a leakdown test to find out where the leaks are coming from - a leakdown puts in compressed air over the whole cycle helping find the leak (but sounds like you are most definitely burning oil through a bad ring)

 

what would be involved in a leakdown test, and can i do it myself? also how would you explain the coolant leak?

 

i'm not exactly sure where you could be losing coolant if you aren't burning it...i.e. through a bad headgasket

1st link explains what a leakdown test is and how you can do it yourself

2nd link explains how you can make your own

The antifreeze could be leaking out only under pressure. Once the car is at operating temp the pressure pushes the coolant out and the heat from the engine or whatever could be burning it off. You can have the coolant system checked with dye and UV light at most shops, the test will tell you exactly where the leaks are if they are not in the engine itself.

 

thx for the advice on that one
