Friends, request guidance for the mechanically impaired.
Vehicle: 2003, 117k miles, daily driven since Dec 02, pulley tune only.
Symptom: quarter size coolant leak on the floor after longer drives & oil cooler soaked in residue and dirt (noticed it since under the car a year ago).
Assumption: oil cooler needed rebuilt with new gasket.
Reality: identified a 1” length section of my head gasket that appears to be leaking
- I have NO oil in coolant nor coolant in oil
- Car runs fine, plugs are clean, no other issues than coolant on the floor infrequently
- Compression test as follows:
1) 165psi
2) 170psi
3) 175psi
4) 165psi
5) 145psi
6) 150psi
7) 155psi
8) 170psi
Question:
- How can I have a leak and still pass a compression test (I assume these numbers are reasonable for a 117k mile car)?
- Considering the aforementioned details, is this critical? Likely to spread?
Thanks in advance
