My valve cover gasket was leaking too, but that was negligible. If your valve cover is leaking there will be oil in the spark plug valley which will eventually damage the boots on the spark plug coil packs if left for a long time.

To give you an idea of how much of a mess vvt-i can cause: My water pump and serpentine belt tensioner were brand new about 10k miles ago. The frame rail and my shock tower used to be white too. If you look on the upper radiator hose it has an area with oil that lands on it.


With the cover removed you can see oil just sits inside on the level surfaces.


Without looking at your car in person I would guess its just your vvt-i gear causing a mess. A leaking head gasket would cause the car to run really funny and eventually there will be signs of oil on your coolant.

Installed rear window visor. Thought it'd be interesting to see an SC with both a sunroof and rear visor, so I installed both. A bit bulky, just for grins.

Thanks for the info! Never knew that was an issue with our cars but I guess most people aren't as lucky to have the 98+ SCs. So...how long did it take to do the repair?

Rebuilt PS pump (easy) and installed it with a driftmotion 2000 PSI power steering line. (Super easy) While installing it I had some questions about the old vacuum lines and what to do with them when putting it all together. so I called them and they walked me through the whole process, giving me a heads upon some installation tips. Seriously those guys are amazing, i'm a customer for life.

It took me 2 days, but a lot of that time was spent under the car with degreaser, rags, and multiple toothbrushes to clean off the grime. If I needed the car back on the road asap, then I could take it a part and reassemble in 1 day. It's basically just a timing belt job with a few more (tiring) steps.

The part I messed up on was trying to remove the cam gears after the timing belt was off. I made the cam move while I was trying to break torque. Removing the cam gear bolt is definitely a 2 person job.

Hooked my GoPro to my front bumper to test it out.

Some more from the other night (on my windshield):

I have a 99 SC300 w/VVT-I Gear and see oil leaking around the front cover. Also, I see oil splattered on a few other areas. So, now I know what I need to get fixed.

Thanks for the post

Do either of you hear faint gurgling/bubbling from the front sometimes when first starting the engine? I'm wondering if it's related or if I just have air in my coolant. I don't think I have a BHG because the car runs fine.

No, I don't hear any gurgling/bubbling noises when first starting up.

Washed and waxed like I do every Friday.. I think it's time to pony up and have it wet sanded and fully detailed for once. :/

I'm glad I could help. I actually bought the vvt-i gear from a vendor on amazon for a lot cheaper than the dealership was asking, so if you're interested in replacing it soon I would suggest looking up the part number on amazon.

Nope, no gurgling sound. I just have some slight chatter from the valves, but that should get quieter with a valve adjustment.

Bleeding the cooling system is fairly easy, so I would suggest doing it to see if the problem goes away.
