Got the same thing. I was just guessing that I am low on oil, quantity wise. It is due for an oil change so I may try a tad bit thicker type. Maybe the lifters are bleeding down???
And I get a "rattle", which only lasts a second or two at a cold startup, or even after sitting maybe 30 minutes. It almost sounds like a bearing knock, but goes away quickly then does not seem come back.
I am going to have an oil analysis done and see what's in my oil.. hopefully no bearing material.
I am still relatively new to these cars, is this just a normal thing with the LC2 engines?

I have a rattle at 150* -160* then goes away I hope it's nothing major? You migh want ( maybe you did already)t to read up about using Mobile 1 synthetic kind of a waist of money
X2 and also I switched from AC oil filter to a NAPA gold oil filter, seems to have helped with the slight start up rattle.

I have the same rattle as well...mine registers on my knock gauge!!
I had a cheap oil filter on it originally (fresh rebuild)....no rattle. Last oil change, I put an AC delco PF47 on and now I have this cold start-up rattle....is there a connection??

I use K&N 3001 oil filter on my VW bug so that made me wonder. Is there a K&N for an '87 TR? Would it have the drain-back feature? I really like the filter they make...
Edit... I guess they do. This looks to be it. I am getting one. Here is the link.

K&N is a champion "performance" design same as the Mobil1. It's expensive for not much gain.

I agree with the above and anti drain back feature is a must, however if you are using sm oil regardless of a flat tappet set up or roller set up be sure to add zddplus which contains the necessary amounts of zddp a proven lubricant for 60 plus years. It may not quiet it completely at start up but will surely reduce it.
Remember when your car was new SF oil had about 1800 ppm of ZDDP and todays oils have between 600-800 ppm.
Product is available from most vendors on this forum.

send me pm with your address will mail you all the tech info on it. ZDDPlus is a lubricant which will protect the extreme pressure points and helps in roller set ups by reducing scuffing and the needle bearings etc.
We have a testamonial from a performance engine shop that builds 1,000 hp engines and tears them down and has seen the results first hand.
I know on flat tappet set ups on cold mornings it has eliminated the lifter ticking I experienced in some of my cars.
Put another way, based on zddp being a lubricant, if you now are using oil that has the SM stamp container on it you only have 600-800 ppm of zddp. When your car was new oil had between 1600-1800 ppm the sf oil. SF will be noted on your visor decal.
Will it remove your rattle? It may not however, it will provide the proper lubrication when added to your sm oil conventional or synthetic.
I even have a testamonial from Dove Manufacturing that is the largest manufacturer of aluminum roller rockers in the US.

Our website may be down but if not you can go to kirbanperformance.com click on the bottle of zddplus and all the tech briefs should be there to see otherwise send me a pm and I will mail you all the data etc....my point being you want to give your oil every advantage possible to avoid wear issues down the road.
Kenny Duttweiler even added it to the Gallina/Freeman race car that pumps out 1,700 plus hp at the GS Nats. I don't think he would have done this if he had any issues with the product.

Even if you were over three quarts low it would not make a difference because the pick up would still be in the oil.
Also, on start up the oil is thicker then it needs to be and a lower first number will flow better on start up. The second number is your operating temp "thickness".
It is not normal to have knock on start up.
