Thanks for all the helpful hints guys. Will put them all to the test. Also, I bought a new filler cap.

I spoke to a volvo mechanic yesterday who said he had seen this one time before. It turns out that the problem is probably not the filler cap/filler neck but instead either a loose cam cover bolt or a small crack in the cam cover. So, I should have an answer to that soon and will post here.

2001 Volvo C70 coupe with built engine and suspension plus 5 speed manual, @400hp at tires. Copious amounts of oil leak out of filler neck, with filler cap and rubber seal in place. It runs all over the surface of the head with gravity pooling it into the cyl 4 and 5 spark plug opening as well as ru...

So, my car is surging, most notably at idle. It runs marginally well under acceleration. It also issued a code P0134 which I found to be a front O2 sensor failure. So I replaced that sensor with a new Bosch 1/2 hour ago. The surge is still present. I cannot find that P1238 code in the Code List on t...

Problem solved. After cleaning and tightening both battery terminals and allowing the car to recharge over 2 days, driving some in spite of the flashing arrow, all idiot lights went out, transmission shifts as normal, car starts every time. All those cars alarms, horn blowing, parking lights flashin...

Book says it is an indication of a fault in the transmission. But there were no faults indicators when I parked it earlier. I then dro...

Earlier today I drove my c70 coupe to run some errands. Came back home and parked the car as usual; locking it up with the key fob button. Tonight around 9pm my neighbor knocks on my door to tell me my car alarm(the beeping is weak) and flashers are going off. I hit the button on my fob and everythi...

So...Thru some trial and error, and conversations with fellow enthusiasts as well as staff at Discount Tire, I have mounted StopTech brakes ST-40 332x32 and found wheels that fit. See photos. My stock rims are 17x7.5 with a 42mm offset. They will fit over the StopTechs...BUT...only with H&R 15mm...

After years of occasional modifications to my beloved 2001 c70 coupe; and because I now get to drive it on a local race course (VIR), I want to upgrade to better brakes. Specifically, I already possess rear 2005 s60r calipers and mounting brackets and will probably purchase Stoptech ST40m 332X32 fro...
