1987 Porsche 911 — intercooler before adding more boost?

Intermittent stuff lies if you only catch it once. A pressure test beats staring at a dry driveway if the 1987 Porsche 911 is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. On “intercooler before adding more boost,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. This is the filter I use when the thread starts repeating itself. Only after sitting overnight so far.

If it were in my driveway, swap the cheap/easy piece first on the 1987 Porsche 911 and see if the fault moves. If the cheap test changes it, stop and reassess. Had a similar mess a couple years ago and that's what finally sorted it. I refuse to clear codes until someone else sees them.

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 1987 Porsche 911 catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. On “intercooler before adding more boost,” that was the fork that mattered for me. Not gospel, but it saved me a headache. This is the version I'd tell a friend.

I wouldn't throw parts yet. Loaded-suspension checks on the 1987 Porsche 911 catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. Run the total, not the monthly, before you commit. Might be overthinking it, but I'd rather overthink than overspend.

I wouldn't throw parts yet. Two 1987 Porsche 911s can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. Time, temperature, and whether it's in gear are the notes that actually help a shop. I'm keeping receipts and dates in one folder.

I'd want a measurement, not a hunch. If a shop can't duplicate it on the 1987 Porsche 911, bring a video plus freeze-frame data, not just a story. You'll know quickly if you're on the wrong tree. Just my two cents from doing this recently. If it repeats twice more I'll book time.

This is usually cheaper to test than to guess. Swap the cheap/easy piece first on the 1987 Porsche 911 and see if the fault moves. Don't erase codes until someone who can help has seen them. Keep sale price, fees, and rate as three different conversations. That's coming from doing this as an owner, not a shop. Trying not to diagnose from the couch.
