What’s up, DOHC? Pontiac Solstice Engine Swap? via CarCraft.com: We just scored a ’72 Vega on eBay, and for the first time, my boy got excited over a car-what a proud day. He just turned 16 and can’t drive until he’s 18, which gives us two years to get it on the road. He is not ready for a 6.0L V-8, but we are drawn to a turbo 2.0L Pontiac Solstice type swap. Fabricating is not an issue, but being a V-8 addict, I am not up to speed on the interchange on the different GM four-cylinder engines, transmissions, turbos, and the like. I personally would choose a five- or six-speed, but the kid may call auto. Any tidbits of info you could supply would be great, maybe contact info for a company that caters to car crafters by supplying complete drivetrain takeout assemblies. I think this has potential to be a great experience with a very entertaining outcome. Jeff Smith: This is uncharted territory, but let’s take a stab at it. It does sound like the least … [Read more...] about Pontiac Solstice Engine Swap & More – What’s Your Problem?

TTAC Commentator KalapanaBlack writes:My mother has a 2001 Oldsmobile Aurora 4.0 with 60,000 miles. There have been four or five problems with it since new, but it hasn’t been as disastrously unreliable as I feared a $40,000 knock-off Caddy would be, especially given the “reliability” of the other K and G-Body sedans.The problem: about two weeks ago, she attempted to roll the passenger side front window down and noticed that it wouldn’t budge. I thought it might loosen up with repeated closing of the door, but that didn’t work. The window lock button is not engaged, and the window refuses to work for the master (driver side) switch or the switch mounted on its own door.The G-Body FWD big sedans (LeSabre, Bonneville, Aurora, Park Avenue) are infamous for their power window troubles, however this is different than anything I’ve heard of. Usually they fall into the door or the motor goes out or the track breaks off.This, however, is stuck all the way … [Read more...] about Piston Slap: Oldsmobile Aurora Window a Real Downer
TTAC Commentator Scorched Earth writes:Hi Sajeev, my buddy has a manual-transmission, non-turbo 7M-GE MKIII Supra with about 150,000 miles. Supposedly the previous owner had replaced the head gasket at least once. About a month ago it started smelling like burning oil, and the engine is known for being overly prone to blown head gaskets, so he decided to play it safe and take it off the road within 2 hours of the symptom appearing.Draining the coolant reservoir revealed a sludgy black substance, which we assumed to be oil, within the coolant. Another strike. The spark plugs, too, were swimming in oil. The rest of the coolant, however, was fine. We could not find any coolant mixed in with the oil, either. Furthermore, there was no greyish/whitish substance around the radiator cap.Still, we went through the arduous process of removing the head. When the moment of truth arrived, the head gasket was found to be undamaged. And at this … [Read more...] about Piston Slap: Essex Archaeology, Scorched Earth Supras
TTAC Commentator sundvl76 writes:Sajeev,Your post of 2 Mar 2011 was a great explanation regarding the cause of the “T” joint oil leak I’ve been experiencing. No one on any of the normal Ford sites has been able to pinpoint the problem, so I thank you for the information. (I’d discovered the source, but didn’t know the cause/fix until your post.) TTAC is now on my Favorites list!So, I am hoping you might also be able to shed some light on the reason for the poor-quality idle I’m experiencing with the same engine. This does not seem to be a mis-fire, but more of a resonant vibration typical of an engine slightly out of time, and/or at the incorrect idle speed. It occurs primarily in colder weather (below 50F) and does improve once the engine is warmed – IF the ambient temp is above about 40F. When ambient is below that point, the strong vibrations do not disappear. Of course it is most pronounced in Drive/Reverse but noticeable in Park/Neutral as … [Read more...] about Piston Slap: A Tribute to the Mariner’s idle Escape?
TTAC Commentator jco writes:Sajeev:In response to your call for more reader-submitted queries, I realized I’ve had one right in front of me and have never thought to ask my fellow TTAC commenters. I have a 2006 Toyota 4runner with the amazing 4.7L 2UZFE V8 engine, currently with 90,000 miles. I purchased the truck with 55,000 miles. However, this motor seems to have a fairly common weakness.The thin-wall exhaust manifolds are prone to cracking at the flange where it bolts up to the head. This engine was used in a variety of ToyotaSome owners have had success in having the dealer replace the manifolds under a TSB related to an issue with smelly exhaust, with the catalytic converters being the source of the smell. On some years of this motor, the first set of cats is the same piece as the exhaust manifold itself and gets replaced as a whole part. And there is a factory emissions warranty running 7 years/100,000 miles. So that’s usually enough to get the work done by the … [Read more...] about Piston Slap: Exhausted after a little Crack?
Patrick writes:Sajeev,My winter car is a 2001 Focus, 170k, duelcam, with a stick. At about 155k the original clutch was replaced. A year and a half later the replacement clutch was replaced. Now the car is in my hands, roughly a year from the previous replacement, and the clutch is in dire need of being replaced. My local trusty mechanic does not do engine and tranny work because he doesn’t want business to back up with tear downs. That’s fine, but I asked his advice anyway.The first symptom was a clunk from the drive wheel when engaging first from a stop. Feathering the clutch and slow on the gas prevents this but is annoying. The second symptom started on the highway, in cruise control, on a rise, the clutch would start to slip. It would rise about 1500 rpm, and then slowly fall back into place. The first has not gotten any better or worse in the last month or so, and the second has gotten to be much worse.So, my question. 3 clutches in 3 1/2 years? I have had a … [Read more...] about Piston Slap: The 3rd Clutch’s the Charm?
TTAC commentator Land Ark writes:Sajeev:I recently acquired a 2007 Honda Civic EX sedan from a neighbor who moved out of the country. I got a really good deal on it and for the most part it’s in good shape. It has 80k miles, 5 speed, and one major flaw. The air conditioning is a little bi-polar; sometimes if blows cold and sometimes not. It always feels cool to cold coming out of the vents but it doesn’t cool the cabin down. It seems to get warm most consistently while sitting still, like at a red light. My first thought was that there wasn’t enough R gas and I would just trundle down to my local big box retailer and pick up some Cold in a Can. But my thinking was that 2007 is too new for it to be out of gas, could it be leaking? I determined that was not too likely since the air coming out was still cold and because the temperature fluctuates and I would think a leak would cause the temperature to remain constant as the gas leaks out until there is no cold air … [Read more...] about Piston Slap: Condensing Honda’s Hot Air?
Doug writes:I have a 2007 Mercedes-Benz S550. I accidentally bought it in 2014 off eBay (long story) for about trade-in ($13,000), with 150,000 miles on the odomater. In a twist of good luck, it turned out to be a one owner car and using CarFax I was able to see and verify that it had been maintained by the selling dealer right up to a few weeks before its eBay appearance. A call to the dealer confirmed the complete service history. Even the brake pads and rotors were new, and it had a newish and very expensive set of Michelins. Almost three years later, it has been very reliable for my teen daughter and has 180,000 miles. It had a few quirks I have fixed myself (clogged charcoal canister, minor trunk leak caused by a missing rubber plug, sticking power driver seat) and only one real repair (dead stereo amp rebuilt by Becker).Now that my daughter is off at college and content with a ZipCar, I am driving it and intend to keep doing so. I have noticed a vibration in the center console … [Read more...] about Piston Slap: NVH Nightmares No More?
TTAC Commentator NotAPreppie writes:Hey Sajeev … or Sanjeev … I’m not feeling picky,Am I insane for considering buying the same Mazda RX-8 twice? Alternate title: A car so nice I want to buy it twice. (Thanks for that – SM)Backstory: Three years ago, I sold my daily driver and autocross car (2005 Mazda RX-8 Sport) to a car club buddy when living and going to school near downtown Chicago meant that it sat in a parking garage for months on end (physical chemistry was intense). I graduated and got a job a year ago and bought a new autocross toy: a 1995 Miata, now with 70k miles.The Miata has turned out to be something of a mongrel. Anywhere fluids can leak, they have. Not having a garage to wrench on the car myself, it’s nickel-and-diming me to death. Also, I’ve discovered that while it’s a Great Car™ during the 60 seconds of an average autocross run, it’s pretty awful to live with day to day. Maybe if I didn’t live in a major … [Read more...] about Piston Slap: A Car So Nice I Wanna Buy It Twice!
