Hi Bricksters,
Need some help/advice from ppl wiser than I....
Background: 87-740T lower radiator hose busted a few min after I parked and sprayed out all coolant. Today I finished replacing lower,upper,and expansion tank hose. Also replaced small hose on flame trap b/c of deterioration. Car had sat ~4 weeks while getting parts and time to fix. Upon start and warmup everything I changed held fine.

Problem: While warming up I began noticing a ping ping sound I hadn't heard (or maybe not noticed) before. Checked oil and it is at the midway mark. No loose screws and fan wasn't hitting the shroud. Drove her over to a DIY Toyota mechanic friend,~3miles away, who said it sounded like the noise was from my lifters. So:

1.) Did something in the block get messed up when the coolant sprayed out?
How could I have messed up something in the block if I was parked?

2.)A search came up with oil pump pickup tubes with bad o-rings introducing air. What is the likeliness of this? If I should check this out what is the actual name of the o-rings(I couldn't find them on IPD site)?

2.) I also looked in the FAQ saw something similar saying it might be the plastic "hushers" around valvev stems. Likeliness of this?

Any other ways I can check to find out the specific problem before I throw money/time at the car? Kinda hesitant to mess with cam area.

Thanks, Servano

I don't recall if these are solid or hydraulic lifters ( a read thru the FAQ's will tell you) - if they are solid lifters there is a certain amount of ticking. They could be out of adjustment.

If you have hydraulic lifters one may have gone flat sitting for those weeks. I had an old plymouth that would have a sticky lifter for about 5 minutes upon first start up of the day. Went on for years. You can buy oil additives that will free up lifters.

You can do the broom handle trick...hold a broom handle to your ear while the car is running and put the other end where you think the noise is...ie go down the length of the valve cover, put it on the water pump etc. Be careful...the engine is running.

B230FTs have solid lifters. Maybe they need adjustment. Sorry I can't be of more help.
